Abstract
In this paper, considering the situation of radar and jammer confrontation, the optimal compound jamming strategy combined with the evasive maneuver of jammer is studied. The performance of compound jamming is improved by proposing an evasive maneuver strategy based on Singer model. Firstly, by selecting the average gate offset distance as the objective function, the optimization problem of jamming method composed of range gate pull off (RGPO) jamming and noise convolution jamming is constructed. Then, in order to improve the jamming performance and save jamming resources, the motion state equation of jammer based on Singer model is established by adaptively adjusting the jammer's acceleration. And the Monte Carlo (MC) method is used to fit the objective function, and the particle swarm optimization (PSO) algorithm is used to solve the optimal jamming strategy. Under the same jamming resources, with this method, the radar tracking gate can be dragged farther and faster. Finally, the effectiveness of this method is verified by simulation.
