Optimized phase-coded waveform design against velocity deception

This paper considers an effective electronic counter-countermeasures (ECCM) technique against velocity deception jamming in multi-target scenario for radar system. The essence of the technique is outlined based on the variations of initial phases of the transmitted pulses in pulse repetition interval (PRI) domain. With the optimized waveform, the false targets generate notches around the true targets in frequency domain. We formulate the multi-target, multi-jamming signal model and derive the cost function for the optimizing waveform design. In addition, we propose a modified Newton method to solve the optimizing problem. Simulations are presented to demonstrate the effectiveness of the proposed method in solving the ECCM optimizing problem for multi-target scenarios.
