FIELD: physics.
SUBSTANCE: method involves exposing objects to a wave on a carrier frequency, receiving the reflected wave in radiation polarisation base, generation of two complex values, a matrix of mutual coherence of the emitted and reflected electromagnetic waves, generation of a differential signal, where the output signal is the differential signal and the matrix Mi is determined using a corresponding formula. The apparatus for realising the method has a transceiving antenna for complete polarisation reception and transmission of a signal, circulators, power amplifiers, composite signal conditioners, low-noise amplifiers, reference frequency generator, frequency converters, matched filters, a subtractor, radio signal envelope detector, a synchronising generator, connected in a certain manner.
EFFECT: possibility of selecting targets with non-mutual radio wave back scattering properties.
