Abstract:

Multi-functional radar is an indispensable and important equipment in modern electromagnetic battlefield. The interference of multi-functional radar is always a difficult problem. In this paper, based on the study of the characteristics of multi-functional radar signal and the radar countermeasure process, the method of joint representation of radar state is proposed, and the interference problem of multi-functional radar is modeled as a Markov decision process with benefits. The cognitive interference decision system is designed. The interference strategy is solved by the cognitive interference decision algorithm based on Q-learning. Through the simulation experiment, it is proved that the cognitive interference decision algorithm based on Q-learning can learn the optimal interference strategy in the absence of prior experience, have the characteristic of "cognition", and have strong adaptability in the unstable environment, which effectively supports the interference decision model mentioned above.

Key words: radar confrontation, Markov decision process, radar state, reinforcement learning, Q-learning
