A robust resource scheduling method of the multi-jammer joint jamming beam and transmitting power is proposed for the problem that some parameters of multi-station radar systems can only be obtained through parameter estimation, and the performance of cooperative jamming is degraded due to the accuracy of parameter estimation. First, the sum of the PCRLB of multiple targets in jamming environment is used to evaluate jamming performance. Then, based on the jamming signal model, radar echo signal model in the suppressive jamming environment, and the geometry of jamming support formation position, the generalization error caused by the uncertainty of radar system parameter estimation is combined with the jamming beam and transmit power to establish a robust resource scheduling method with jamming resource constraints. Finally, due to the coupling of resource parameters, a two-step decomposition solution based on genetic algorithm is used to solve it. The simulation results show that the proposed robust resource scheduling strategy can effectively reduce the performance of multi-target tracking in radar systems and enhance the cooperative jamming performance of multi-jammers to the radar systems.
