Abstract:

The netted radar scintillation detection system can improve the cooperative detection performance and survival rate of radar. It is an urgent problem to select a suitable radar cooperative detection startup and limit the startup exposure time of a single radar to adapt to the ever-changing environmental threats. In this regard, a netted radar scintillation detection scheduling method is presented based on deep Q-learning (DQL) reinforcement learning algorithm to limit the startup time of a single radar. Firstly, the threat degree model of the air jammer to the netted radar and the scintillation detection model of the netted radar to the air jammer are established. Then, the reinforcement learning reward function of the threat degree and the netted scintillation detection probability is proposed. Finally, the optimal scintillation startup decision scheduling scheme of the netted radar is obtained by using the proposed DQL algorithm. The simulation results show that the average benefit rate of the proposed DQL scheduling method is superior to random scheduling, artificial bee colony scheduling and double deep Q network(DDQN) scheduling methods, and the scheduling response time is less.

Key words: netted radar, scintillation detection, reinforcement learning, deep Q-learning (DQL), double deep Q network (DDQN
