Range-velocity jamming suppression algorithm based on adaptive iterative filtering

We consider the suppression problem of rangevelocity deception jamming based on adaptive iterative filtering algorithm for pulse Doppler (PD) radar. First, we present the real target signal and false target signal model based on digital radio frequency memory (DRFM). Then, we suppress rangevelocity jamming by adaptive iterative filtering algorithm in range dimension processing and Doppler dimension processing for target signal and jamming respectively. At the stage of analysis, we consider multiple real targets and false targets in range-Doppler plane, and evaluate the suppression performance of the proposed algorithm by simulation. The results highlight that the proposed algorithm will converge fast and yield an excellent suppression performance.
