The invention relates to digital computing, and in particular to digital computing systems for processing the input information about the characteristics of agents (BSR) heterogeneous groups, transforming, selecting the appropriate strategy, definition of outcome (win, lose, parity) fighting (DB), assessing their losses and inflicted damage to the enemy when choosing the optimal and suboptimal strategies by both parties. It can be used command staff of the Armed Forces in the process of learning and relearning, conducting command-staff exercises and training, as well as directly to schedule group fighting (HBB) with heterogeneous groups. The technical result is an expanding Arsenal of technical means to improve the combat effectiveness and impact due to the proposed method of learning the specifics of the action with heterogeneous groups, conducting command-staff exercises, planning and creation of devices to choose the optimal strategy on target when writing in an uncertain time opponent of the provision in terms of fighting heterogeneous and homogeneous groups.

The known method [1-4], which reveals the dynamics DB one group against another and allows up to its holding to call b the previous winner, which the action of homogeneous groups is not new. The parties have heterogeneous groups (WG) A, B1In2makes the situation not so straightforward. In the scenario of fighting the WG major role in the choice of strategy is not the number of agents in each group [1-4], and the ratio of the intensities of their destructive fire [5-6].

When the database heterogeneous groups experience the following problematic issues:

1) are there optimal strategies in database heterogeneous and homogeneous groups in terms of input lag reserve?

2) how does the lag from input provision on the choice of strategy database?

3) what is the difference picture lag input provision heterogeneous BSR from a uniform?

4) how does the choice of strategy for the management database with heterogeneous and homogeneous BSR?

5) whether the party And in the presence of heterogeneous and homogeneous groups to adhere to the rules of the destruction of the first strong group and weak then?

The presence of heterogeneous BSR the parties and the delay input backup grouping makes it difficult to answer all the questions.

Consider the scenario of a military confrontation (Bps) of the parties with heterogeneous grouping, assuming the availability of a reference database of each group with any group opposing party.

Are the same patents [7-10], aimed at the creation of instruments of acceptance and implementation of targeting, which do not resolve the deficiencies and do not solve formulated by the authors of the task.

Therefore there is a need to develop such a method and device that would provide the answer to the problematic issues.

In contrast to the known ways of doing DB increase combat effectiveness in the present invention is carried out at the expense of knowledge and accounting:

- performance heterogeneous BSR members of all factions of the parties;

the effect of the choice of the optimal and suboptimal strategies of doing the DB parties a and b with homogeneous and heterogeneous grouping;

the effect of the level of input lag reserve on the results of the database for different types of groupings;

- the influence of more powerful groups on the choice of strategy in the database heterogeneous and homogeneous BSR;

the outcome of the ongoing hostilities prior to the event (which side would win), forecasting the price of victory over the enemy (their loss), in case of defeat - cause maximum damage to the enemy with determination of the number of remaining unaffected BSR at different strategies of the parties, the heterogeneity or homogeneity BSR and lag up the enemy.

According to the invention the technical result is achieved by the fact that the comma is irout information about the performance capabilities of each party, remember her in the first memory block, wherein the complement her performance groups from the reserve of the variable type, use the information on munitions of all groups for a preliminary assessment of the characteristics of their heterogeneity and determine the coefficients Autonomous military superiority of the hand And over the groups B1In2and finding distribution coefficients agents when shooting for groups B1In2using the received information, carry out the strategy choice of hostilities, define the remains of agents all groups during and at the end of hostilities, remember interim characteristics of the groups and the results of the outcome of the fighting, remember them in the second memory unit, reads from it and sent to the inputs of the block visualization, which displayed information about the results of the fighting parties And: victory, defeat, parity, the balance of capabilities in the groups and on the intermediate characteristics of groups: type of strategy, the delay of input provision, type of heterogeneity, size combat odds superiority and distribution coefficients agents (figure 1).

The method consists in the following.

Known mathematical description of bilateral DB using diff the account of the differential equations of dynamics DB [1-4]. Each of the two sides a and b includes the grouping of homogeneous BSR. Pursued the task of input provision [3] homogeneous grouping.

Of interest is the consideration of bilateral database with heterogeneous and homogeneous groups, to identify differences in approaches to the choice of strategies. The party includes two heterogeneous groups B1and B2. BSR side As before (t≤0) and during (t>0) group database are characterized by the following indicators:

M, m(t) is the original and current (during DB) number of agents of group A;

µ1=p1f1, µ2=p2f2- the intensity of the destructive fire BSR group And proportional to the probabilities of damage BSR one shot R1p2and their korostelina f1f2conducted by BSR groups B1and B2;

Group B1and In2the parties have similar characteristics: N1n1[t], N2n2[t], λ1=q1g1, λ2=q2g2.

For clarity assess the impact of each strategy on the results of the database will give the characteristics of the BSR numerical values shown in table 1A.

In the last column (5) shows the condition of heterogeneity [5-6] - inequality works (P1P2)

Formula: (1B) requires the destruction in the first place, group B1; (1G) - requires destruction, first of all, grouping In2; (1D) - indicates the presence of homogeneous groups that are insensitive to the choice of a strategy.

Calculated by the well-known formulas [1-4] table 2A shows offline coefficients Ki(i=1,2) the military superiority of the parties And in relation to groups B1and In2characterizing predictable outcomes database:

- bringing the database offline (separately) or group B1or2the victory will be on the a-side, because

K1>1 and K2>1;

- due to the fact that K1=1.57, and To2=2.89, this means more than half the combat superiority of party a relative to group B1and almost three times the combat superiority of the parties And in relation to the grouping In2;

Table 2A
Criteria of excellence sides And over heterogeneous groups B1and In2

in other words, the grouping B1is the stronger side And compared to the In2. Using available [1-4] formula for offline database with group B1we see that when the Autonomous destroying its BSR (n1[t]=0), loss of party a is 8 BSR. In the case of Autonomous defeat grouping B2(n2[t]=0) side And lose only 2 BSR (the argument tindicates the end time of the database).

Source based heterogeneous BSR before the database

The original equations (2A)-(2G) before doing the DB 3 groups are presented in the following form:

m'[t]-(λ1*n1[t]+λ2*n2[t]), (2a)

n1'[t]-μ1*r1*m[t],(2b)

n2'[t]-μ2*(1-r1)*m[t],(2in)

m[0]=M,n1[0]=N1,n2[0]=N2,{m[t],n1[t],n2[t]},t].(2g)

The solution of the differential is ravneny (2A)-(2G) using the software complex Mathematic (PCM) allows you to define formulas dynamics DB 3 groups of parties (3A)-(3G).

r1+r2=1;ω=r1λ1μ1+λ2μ2*(1-r1)-{m[t]=MCosh[tω]-((N1λ1+N2λ2)/ω)*Sinh[tω],(3a)n1[t]=1ω2*(-N2r1λ2μ1+N1r2λ2μ2+r1(N1λ1+N2λ2)μ1Cosh[tω]-mrow> (3b)Mr1μ1ωSinh[t*ω]),(3in)n2[t]=(3g)1ω2(N2r1λ1μ1-N1r2λ1μ2+r2(N1λ1+N2λ2)μ2Cosh[tω]-Mr2μ2 ωSinh[tω])}.

Explain the meaning of some symbols and expressions given in the formulas (3A)to(3G):

* is the multiplication sign (or space), adopted in RMB;

Sinh[t*ω], Cosh[t*ω] - values of the hyperbolic sines and cosines;

M, N1N2- the initial value BSR groups A, B1In2;

m[t], n1[t], n2[t] - current (during run DB) values BSR groups A, B1B2;

m[t], n1[t], n2[t] values of the remaining BSR groups A, B1In2after the database;

r1, r2- the relative coefficients BSR hand And determining the number of BSR firing in groups B1B2equal to r1=M1/M; r2=M2/M. of Course, that r1+r2=1 and M1+M2=M. In our example, to determine, for example m[τ0]=6 if strategy S0,

r1=1/(1+μ1*N2/μ2*N1).(4)

Note the universality of the ratio r1in formulas (3A, b, C, d):

- if you put r1=1, then implemented the strategy S12;

- if you put r1=0, then implemented the strategy S21.

Strategy the DB side And

Highlight three strategies of the parties And [5-6]:

- S12- party And first destroys stronger (superior) group B1and then weaker - B2;

- S21- side a first rapid-fire destroys more than group B2and then less than - B1in which λ2µ2=0.013>λ1µ1=0.0099;

- S0- side And destroys groups B1and B2at the same time, by selecting the appropriate values of r1(4);

- S1- side And destroys only the grouping of B1. It is a subsidiary, first, with the delay group B2side a starts to DB only with group B1before the advent of the reserve, secondly, it is necessary to determine the scale of input lag reserve side Century.

Input lag reserve side In

In front of the face And is group B1. From the reserve hurry grouping B2time τγinput (lag) which may be carried out in the period 0≤τγ≤t1∞. The value of time t1∞reflects the end of the DB side And with the group what irokoi B 1. In principle, it is possible to trace the influence of time lag τγthroughout the period, which is rather cumbersome, but we will restrict ourselves to only three (γ=0; 0.5; 1):

- τ0=0 - zero time of input a backup group B2. Both groups are in a state of instant and simultaneous start the database by the parties at the time t=0;

- τ0.5=0.5t1∞- enter the backup group B2half time from offline destruction grouping t1∞B1;

- τ1=t1∞- type of backing groups In2is carried out at time t1∞battery destruction grouping B1.

Using the original data BSR sides (table 1A), with regard to time period 0≤τγ≤t1∞lag input group2solving equations (3A)-(3D), we get the remnants of the BSR after the end of the database is given in table 3 heterogeneous and homogeneous groupings for the three strategies, the DB side A.

According to the results of table 3, graph (figure 2) residues BSR depending on the time τγdelay input reserve side In and strategies in the DB side A. the Graph shows:

for heterogeneous groups most severe (loss of the large side And is the process of conducting simultaneous striking of fire in the both groups B 1In2when τ0=0;

of course, as to the parties And the most responsible when τ0=0 is the choice of the optimal strategy S21. The range of parties And large: from defeat (when choosing strategy S12) to win (if strategy S21);

from the graph we see that the strategy S0takes the results of a DB intermediate location and depending on the amount of r1can approach or strategy S12or strategy S21;

- with increasing time τγlag input provision BSR relevance of the choice of strategy is maintained for a period τ0≤τγ≤0.5t1∞, further decreasing to zero when τγ=t1∞.

To compare the influence of the choice of strategy when DB homogeneous groupings with initial data close to the example above, by modifying their values (tables 1B and 2B)with homogeneous grouping.

Comparison of tables 1A, 2A tables 1B and 2B speaks of the close similarity between heterogeneous and homogeneous groups. The only difference lies in the inequality of works (table 1A) WG

0.09*0.11=0.0099<0.1*0.13=0.013

and equality (table 1B) for homogeneous groups

0.1*0.12=0.012=0.096*0.125=0.012.

Figure 3 presents and the alogical figure 2 curve of m[t]=f(τγdepending on the change of the time delay input backup grouping in terms of DB homogeneous groups. Significant differences from figure 2 in the DB OG will be:

- the curve has no socket, i.e. no influence strategies S12, S21, S0the outcomes database;

curve resembles the lower part of the socket of the first curve (figure 2), i.e. its worst strategy - S12.

So, in the application disclosed the need to identify heterogeneous groups, factors which formula (1A), allows to determine the inequality λiµijµjto select the optimal strategy - the initial destruction of all means the j-th group (2) enemy. Further the destruction of the remaining groups B1. The price of the optimal strategy Sji(S21- the winning hand (see figure 2), the optimal strategy S12it leads to the lesion (figure 2) when τ0=0.

If the conditions database contains a homogeneous group, all strategies are equivalent and give the same result. For all strategies, the curve in figure 3 is the merge of all three curves, available in figure 2, in one.

The increase of BSR hand And after the end of hostilities, depending on the increase of the level of input lag reserves is the heterogeneous and homogeneous is upperback - almost the same character. However, using a database of homogeneous groups repeats the change in stocks BSR when choosing the worst strategy in action heterogeneous groups.

The importance of the choice of the optimal strategy at the beginning of hostilities heterogeneous groups is very significant (from defeat to victory side A) - see figure 2. In further - higher input lag reserves value selection strategy is slightly lower, and by the end of the DB role of any of the strategies becomes equal.

2. The device for implementing the method according to claim 1, depicted in figure 1, containing the switch 1 and the first memory unit 2, characterized in that its composition unit 3 assessment of the characteristics of the parties, block of 4 selection strategy, block 5 of the balances of military means, the second memory block 6, block 7 visualization and control unit 8, and the outputs of the switch 1 is connected to the inputs of the first memory unit 2 connected by its output to the input of unit 3 assessment of the characteristics of the parties and with one of the inputs of block 5 of the balances of military means, the output of unit 3 assessment of the characteristics of the parties connected to another input of block 5 of the balances of military means and to one of inputs of the second memory block 6, the output of block 5 of the balances of combat means connected to another input of the second memory block 6, the outputs of which are connected to suitable the and inputs of block 7 visualization, unit 8 manage their outputs connected to all the control inputs of the blocks 1-7, block 7 selection strategies associated two-way communication, the outputs of which are connected to respective inputs of blocks 2, 3 and 6.

The device may be used for operator training, combat missions and for research purposes.

The device allows you to determine the remainder of the BSR sides a and b in the following scenarios:

- in combat heterogeneous groups;

- in combat homogeneous groups;

- with input provision in any time τγ;

- if you select any of the 4 strategies S12, S21, S0, S1.

In accordance with figure 1 of the original values BSR all groups of parties a and b (B1B2), as shown in table 1A or 1B, enter the inputs of the switch 1 and the control signal from the control block 7 is fed to the input 9 of the first memory unit 2.

The purpose of a preliminary assessment of the characteristics of the parties on the signal from unit 4 selection strategies selected strategy S1- bilateral DB with the main grouping B1and fixed the date of its complete destruction t1∞knowledge of which allows to determine the real interval 0≤τγ≤t1∞possible input provision.

In block 3 according to the formula (1A) is determined not the only heterogeneity (homogeneity), but the relation (1B, d, e) firing korostelina groups. Note that each of (1B, d, e) ratios determines the optimal strategy. But in unit 4 selection strategies for research purposes you can choose and suboptimal strategy.

Computing in block 3 of the coefficients K1To2the formulas are given in tables 2A and 2B, judge Autonomous combat superiority in all three groups.

The determination in block 3 by the formula (4)r1*allows you to properly form pseudophyllinae strategy S0. The deviation from it brings the database to the strategies S12or S21.

Depending on the chosen strategy Sijand value of the lag time τγthe relevant data according to control commands from unit 4 selection strategy and unit 8 of the control enters the block 5 balances BSR.

In unit 4 in accordance with the original data (tables 1A, b; 2A, b), equations (2A-g) and their solutions (3A-g) is the definition of residue (losses) BSR parties.

With regard to the original data table 1A figure 4 shows the change in the BSR of the parties to the strategy Siand figure 5 for strategy S0.

In the same way it was made the decision and for other scenarios, the end rezultatelor are shown in table 3.

After the end of the simulation database remains BSR hand of the winner and zero defeated BSR enter the second memory block, and stored together with the characteristics preliminary assessment of the parties.

After graduating from the database of the parties at the panel visualization can be observed main results:

results DB: victory party And the defeat of party a, the parity in the database;

- the remains of the BSR m[t], n1[t], n2[t] all groups of parties: A; B1and In2;

and intermediate results.

- selected strategy Sijparty A;

the time τγlag input provision In2party;

- classification of groups (WG or CG);

- Autonomous factors martial superiority To1To2the sides And over the groups B1and In2;

- r1, r2, the relative ratios of redistribution BSR parties And groups B1and B2and several others.

Note that the consideration of heterogeneous and homogeneous groupings in combat allows to draw the following conclusions:

1) the limited warranty are a particular case of hostilities heterogeneous groups, and change strategies does not affect the results of the DB OG;

2) from a variety of all strategies for WG homogeneous groupings inherent only is about the worst (compare figure 2 and 3);

3) when you enter the reserve, the most equally important for RG and OG the situation is the lack of lag, which leads to the defeat of the party And when OG and RG - if you choose the worst strategy (compare figure 2 and 3).

4) the choice of the optimal strategy for the WG leads to the victory of the party And not only in the absence of lag-up opponent. In other cases, the input lag of the reserve side And has a considerable advantage in the preservation of their BSR compared with other strategies of heterogeneous and homogeneous groups (figure 2 and 3).

Implementation of the proposed method and device in the first stage possible in the form of hardware and software on a laptop in a military execution, and the second as a stand-alone device.

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine. In method realisation probing by means of ultrasound signal, directed to area of fetus heart location, is carried out. Reflected Doppler signal is amplified and converted into digital form. Ultrasonic irradiation signal represents series of pulses, where frequency of their repetition equals carrier frequency of ultrasonic signal and is determined depending on maximal depth of probing. Amplification of signal is first performed in frequency band, consistent with duration of series of irradiation with discretisation frequency, corresponding to band of received signal. Transfer of Doppler signal spectrum on zero frequency and accumulation of complex signal counts in accordance with position and size of measured volume by probing depth are performed. Filtration of Doppler signal in specified frequency band is carried out. Search for peaks of autocorrelation function is carried out and distance between them is determined. Doppler shift is calculated on the basis of calculation of difference of phases between Doppler signals from successive series of ultrasound signal. Width of spectrum of Doppler frequencies and energy of Doppler signal from all sections of probing depth are evaluated. After that, control of parameters of Doppler signals from entire probing depth is performed, for which purpose separation of sections of probing depth, related to fetal heartbeats is carried out on the basis of the analysis of parameters of spectrum of Doppler frequencies. After that, adaptive reception gate for signal of fetal heartbeats is formed, in accordance with which the following corrected ultrasound signal is formed.
