Parameters design and signal processing algorithm research in clutter based on the stepped frequency waveforms

Aiming at the detection and imaging of targets in clutter, the parameters design and the optimization criterion based on the stepped frequency waveform were given. Meanwhile the signal processing algorithm was proposed, which includes the method of measuring the radial velocity based on the frame PD processing, and the follow-up processing of echo reconstruction and synthesizing high range resolution (HRR) profiles. At last, combined with the parameters of a real radar system, simulation results validate the effectivity of the algorithm and the ability of extracting target information and synthesizing the one-dimension HRRP under the clutter background.
