Optimized Phase-Coded Waveforms Design Against Range Repeat Jamming

This paper considers an effective signaling scheme to combat the range repeat jammer for radar system. Robustness against jammer is achieved by designing different phase-coded pulses with weighted auto- and cross- correlation in a coherent processing interval (CPI). In this way, the matched filter output forms notches around the true target so that the true target can be indicated clearly. In the same time the jammer is suppressed for the good cross-correlation property between pulses. To obtain the desired waveforms, we formulate the penalty function and propose the pattern search (PS) method to optimize it. Finally, we present simulations to demonstrate the effectiveness of the proposed method.
