FIELD: radio engineering, communication.
SUBSTANCE: high probability of detection is achieved using novel operations for polarisation-sensitive nonlinear iteration processing of radio signals, which increase sensitivity and the dynamic range when forming horizontal and vertical polarisation components of a two-component complex frequency-time image of radio signals scattered by objects in the analysed region of Doppler frequencies and time delays.
EFFECT: high probability of detecting remote and weakly scattering objects.
