Jamming Resource Allocation for Multi-jammer Cooperatively Suppressing Netted Radar Systems

In this paper, aiming at the scenario of the escort support jamming (ESJ) formation reconnoiters the netted radar system (NRS), a joint jamming beam assignment and power allocation (JJBAPA) strategy is proposed for multi-jammer cooperatively suppressing the NRS. First, we establish the radar echo model based on the transmitted suppressive jamming signal and the geometric position of the NRS and the ESJ system. Then, according to the characteristics of the radar echo, the detection probability of the NRS is derived and used as a performance metric to quantify the detection performance of the NRS. Finally, combined with the practical jamming resource constraints, the JJBAPA optimization problem is formulated and solved. To allocate jamming resources reasonably, we consider the frequency alignment problem between the radars and the jammers. Simulation results verify the effectiveness and superi-ority of the proposed JJBAPA strategy in terms of degrading the detection performance of the NRS.
