This work concentrates on the suppression of deceptive jamming generated by digital radio frequency memory (DRFM) in multistatic radar system. First, we model the received signal model in the presence of deceptive jamming based on the properties of the radar target and the deceptive jamming in time and frequency domains. Then, we propose the suppression approach of the deceptive jamming based on three...
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...
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...
