Abstract
Window functions are used in the radar signal processing to reduce the undesirable effect of masking a weak signal of a moving target with powerful reflections from stationary or slow-moving objects. The effectiveness of window functions weakens in radars which transmit and receive signals with pseudo random amplitude and phase-shift keying on common aerial. The article shows that pseudorandom pauses between phase-manipulated pulses of pseudo random duration affect the result of window weighted processing. The best parameters of the probing signal for weighing them by window functions during fasttime and slow-time processing are determined. An algorithm for normalization and interpolation of compressed segments of the signal with pseudorandom amplitude and phase-shift keying is proposed. The results obtained are confirmed by modeling the processing of an additive mixture of echo signals with different Doppler frequencies.
