DETECTION AND LOCALISATION METHOD OF AIR OBJECTS Russian patent published in 2012 - IPC G01S13/04 

FIELD: radio engineering.

SUBSTANCE: effect is achieved owing to selecting object illumination transmitters emitting linear-frequency-modulated radio signals, using radio electronic compensation operations of incoherent interference from multiple interfering transmitters, using radio electronic compensation operations of strong straight multi-beam radio signal of illumination transmitter, which is additional coherent interference masking weak dissipated signals, as well as using operations of adaptive spatial filtration providing the directional reception of useful dissipated signal in the specified direction with simultaneous suppression of interference of wide range, which come from other directions.

EFFECT: increasing detection sensitivity and accuracy of spatial localisation of wide range of air objects in conditions of multi-beam propagation of radio waves.
