FIELD: physics.
SUBSTANCE: existing apparatus for classifying objects further comprises a pulsed generator, a block of delay lines having (M-1) delay lines, where M is the number of pulse sequences used, characterised by the frequency step from pulse to pulse, a block of frequency multipliers having (M-1) frequency multipliers, a third mixer, a carrier frequency generator and a coherent heterodyne. Inter-block communication and the principle of operation of the classification apparatus are changed in a suitable way.
EFFECT: high probability of correct classification of aerial objects experiencing random oscillation on yaw, pitch and rolling angles when exposed to a sequence of probing radio pulses on different frequencies.
