METHOD AND DEVICE FOR RECOGNIZING AIRPLANE DESTRUCTION Russian patent published in 2018 - IPC G01S13/52 

FIELD: security facilities.

SUBSTANCE: invention relates to systems for detecting objects by reflecting radio waves from the surface of said objects and can be used in radio location to recognize the destruction of an aircraft. Technical result is achieved by the fact that in the method for recognizing the destruction of an aircraft, which consists in emitting an electromagnetic energy in the direction of an airplane, receiving signals reflected from the aircraft, obtaining a spectrum of the reflected signal, carrying out a narrow-band filtering of the Doppler frequency components, additionally determining the presence of the Doppler frequency at a frequency caused by movement with a speed close to the velocity of the shock front, ensuring its reproduction, indicating and signaling on the presence of this signal. Device implementing the method comprises a series-connected antenna and a radar, a filter tuned to the Doppler frequency caused by movement at a speed close to the velocity of the shock front, a speaker, a detector, a threshold device and an indication circuit, the filter input being connected to the output of the radar, the output of the filter is connected to the inputs of the speaker and detector, whose output through the threshold device is connected to the indication circuit.

EFFECT: achieved technical result – provision of the possibility of recognizing the destruction of an aircraft.
