Abstract :
In this paper, a novel approach is proposed to canceling clutter in high pulse repetition frequency (HPRF) stepped-frequency radar by utilizing the Doppler spectrum diversity between target and clutter, via the DFT of the data within different bursts at a same carrier frequency. Both the signal processing steps and particular parameters design rules are brought forward in detail. The simulation results show, it is not subject to the product of pulse width and frequency step size. Even if the target is masked by the clutter in range profile, it also can obtain both high detection performance and fine high resolution range profile (HRRP) with lower SCR or SNR.
