Thus, the proposed device meets the criterion of "substantial differences".

In electronics and underwater acoustics is widely known use of the hydrophone, decoder, key, radio, flashlight, timer, block radio reception unit to determine the distance to its source.

Thus, the presence of "new material" signs, in conjunction with well-known, provides the appearance of the proposed solutions new properties that do not match the properties of the known technical solutions with high noise immunity and reliability remotely disconnect scuba product and identify its location on the sea surface, which allows to conclude that the proposed device has an inventive step. When you do this:

FIELD: protection aids.

SUBSTANCE: direction finder can be used for taking azimuth relatively guarded objects at guarded areas, calculating number of objects in group target and classifying found objects. Direction finder has two seismic receivers, two processing channels with delay lines and correlators, maximal signal selector, correlator, testing module, commutator and calculator. To realize the direction finding function the method of passive diversity detection and ranging is used. The main information criterion for finding direction to object has to be the function of mutual signals correlation in two signal processing channels. Value of azimuth is judged from value of signal delay. Change in value of signal delay is equivalent to controlling directional diagram of seismic active aerial which allows classifying detected objects separately. Test influence is used for adaptation of speed of propagation of seismic wave which changes under influence of meteorological conditions. Current value of speed of propagation of seismic wave is judged from time of delay of test influence signal coming to second seismic receiver. Tuning of lines of delay is conducted correspondingly to those changes.

EFFECT: improved precision of direction finding.

SUBSTANCE: the problem of identification of bearings of radio sources in the claimed method is solved as follows: on the basis of the values of bearings of radio sources measured in each of two receiving positions and own co-ordinates of the receiving positions the altitudes of the radio source with respect to each receiving position are found, then the difference of these altitudes is found. On the basis of dispersions of the errors of determination of the bearings of the radio sources in each receiving position the value of the identification threshold is determined. By the results of comparison of the mentioned difference of altitudes with the identification threshold a decision is taken on belonging of the bearings, measured by different receiving positions, to one radio source.
