DETECTION AND DIRECTION FINDING METHOD OF AIR OBJECTS Russian patent published in 2011 - IPC G01S13/02 

FIELD: radio engineering.

SUBSTANCE: increase in detection sensitivity and direction finding accuracy of air objects under conditions of multi-beam propagation of radio waves is achieved owing to using radioelectronic compensation operations of strong forward multi-beam radio signal of illumination transmitter, which is additional coherent interference masking weak dissipated signals by means of identification and measurement of parameters of signals of coherent interference and subtraction of signals of coherent interference from the signals received with each antenna.

EFFECT: increasing detection sensitivity and direction finding accuracy of air objects under conditions of multi-beam propagation of radio waves.
