Group of inventions relates to methods of active resistance means of defense and is designed to protect aircraft, such as airplanes and helicopters and other moving objects.

Known complexes counter placed on aircraft and helicopters, such as the IL 76 MD SUT Russia, the helicopter an-1F USA, consisting of station radio intelligence station infrared (IR) detection palengat in radio and infrared bands, analyze the data and make a decision on combating stations interference in the radio, infrared ranges, shooting spending transmit data on the use of standard weapons. (Y. Gordiyenko Century and other Military aircraft. T. 1 S. 6, 158 and 249. LLC “Potpourri” 1999).

The disadvantage of these devices and how they can be applied are the lack of accurate data about distance, speed, and direction of air defence assets and, as a consequence, the impossibility of identifying the most dangerous tools, which you want to create opposition, and the optimal time of its creation.

The closest in technical essence is a complex helicopter A USA. (Y. Gordiyenko Century and other Military aircraft. 1999, LLC “Potpourri”, T. 1 S. 121 and 122), in which the receiver warning radar and laser irradiation and IR-radiation device for creating PC-interference accept signals from air defense, analyzes signals on-Board electronic equipment with reference to navigation and delivers the command to shoot dipole reflectors, creating a counter station interference in radio and infrared bands.

The disadvantage of this device and method of its use is the lack of accurate data on DALnet means, you want to create opposition, and the optimal time of its creation. In addition, the radar station (radar) used to review the space and weapon guidance systems, consisting of transmitter and receiver device, data processing, have a narrow (up to 10%) frequency ranges, are not intended to create noise and interference signals to the air and have low immunity.

The present invention is to increase efficiency of anti-air defense by obtaining accurate data about distance, speed, and direction of air defense, as well as improving the noise immunity and reliability of the protection device.

This problem is solved in the proposed group of inventions, in which the method of counteracting means AA is characterized by the fact that passively palengat air defense means in the radio and optical ranges, analyze the data computing device and serves the team to counter active stations interference in optical and radio frequency energy in the direction of air defense, the device emission spending and transfer data on the use of standard weapons, before giving commands to counteract additionally formed the AI antiaircraft defenses, take a passive DFS reflected signals to determine the distance, speed, position and direction of convergence with air defenses, in addition, to improve the noise immunity and secrecy work in the optical range using the untapped ranges (e.g. UV), emit signals of sufficient power to determine the induced optics “flare”, and radio emit radar signals at a frequency different from the accepted funds from the defense, at the time determined by the direction finder, when the antenna device air defense focused on the direction finder.

The described method is implemented using a device that includes passive DFS in the optical and radio ranges, the active station interference in radio and optical ranges, the device emission spending connected with the computing device having a communication channel with the device management standard weapon and which is additionally provided with a device for forming and processing radar signals, connected to the computing device, inputs the active station interference and outputs passive direction finders in the optical and radio ranges.

The group of inventions is illustrated in scheme is ATOR microwave 2 - direction finder optical range, 3 - input, 4 - station interference optical range, 5 - station interference range, 6 - ejection device spending, 7 - communication device with a standard weapon, 8 - forming device and processing the location signals.

The device operates as follows. DFS 1, 2 take in passive mode and palengat signals from air defense, with this information, the calculator 3 analyzes the situation and issues on device 8 teams on the refinement of defence facilities, these commands station interference 5, 4 at radio and optical wavelengths emit signals in the direction of a means of air defense, DFS 1, 2 takes the reflected signals and transmit the device 8, where the specified data on the rate of convergence, distance, coordinates, and direction of air defense means. Additional data comes in the transmitter 3 for analysis and command counter stations active noise 4, 5, 6, 7. For increasing secrecy in locating mode in the optical range using the untapped ranges (e.g. UV), emit signals of sufficient power to determine the induced optics “flare”, and radiate radio frequency energy location si is trojstva air defense focused on the direction finder. Thus due to the “glare” from induced opto-electronic devices in the optical range, and radio frequency energy induced from the antenna increases the detection range air defense under the proposed method. In addition, given the high broadband stations interference in the radio band (2-2,5 octaves) unlike radar (up 10%) and in the optical range (from 0.2 to 14 microns), the implementation of locate mode has a greater opportunity for the offset from intentional interference.

The proposed method and the device will enhance the survivability of aircraft, to provide a reliable protection against air defense systems, to improve the noise immunity of the system.
