Abstract For the compensation of the system distortion in the wideband radar working with STRETCH processing, a new distortion compensation method based on time-variant property removal is proposed. The STRETCH processing distortion and its time-variant mechanism is expounded in detail, and a time-variant property removal algorithm is obtained. Joint time-variant property removal and distortion compensation method is established finally. The concrete implementation steps of this compensation method are also presented. Experimental results based on the real data, which prove the effectiveness and efficiency of the presented strategy, demonstrate that the proposed compensation method can compress echo pulse with low computation complexity, simple implementation and sidelobe suppression above 45 dB.
