In order to study the jamming resource allocation problem of UAV clusters to radar clusters and to maximize the utilization of jamming resources, we established a cooperative jamming suppression effectiveness model with clear constraints and suitable optimization objective functions. We simulated the allocation of jammer resources, basing on radar threat level and jamming effectiveness matrix with the objective of maximizing jamming effectiveness to radar clusters, using intlinprog function, improved PSO and GA, which adopts traversable boundary and binary coding mode respectively. The simulation results showed that the expected effectiveness on jamming resource allocation can be achieved by both improved algorithms.
