Deception Jamming Against Multistatic Radar System Based on Periodic Multiple Phases Modulation

Aimed at the problem that the correlation between the false targets (FTs) amplitudes among the receivers of the multi-static radar system (MSRS), a cooperative deception jamming method with multiple jammers based on periodic multiple phases modulation (PMPM) is proposed in this paper. In the distributed jammer system, each jammer adopts the PMPM jamming method with different parameters, and then jointly transmits the beam to forward the jamming signal. Finally, the amplitude of the FTs between the receivers is affected by the combination of the azimuth angle and the phase modulation coefficient, which breaks the correlation of the FTs amplitude between the receivers. Aiming at the problem of obtain stable and optimal jamming effects, a jamming modulation parameters optimization method based on genetic algorithm is proposed, the detection probability of the physical targets (PTs) is always 0%. The effectiveness of the proposed method is verified by simulation.
