Multifunctional radar cognitive interference decision-making method based on threat assessment

The invention discloses a multifunctional radar cognitive interference decision-making method based on threat assessment, which is applied to the field of radar interference and aims at solving the problem that the threat of an existing multifunctional radar to a target is relatively high. According to the multifunctional radar cognitive interference decision-making method, firstly, an interference decision-making problem is modeled into a Markov decision-making process with benefits, meanwhile, a track-based multifunctional radar threat assessment model is established, and a threat assessment result is used as a basis to obtain a benefit function of interference decision-making. And finally, solving the problem by using a reinforcement learning algorithm Q-Learning to obtain an optimal interference strategy. 本发明公开一种基于威胁评估的多功能雷达认知干扰决策方法，应用于雷达干扰领域，针对现有多功能雷达对目标的威胁较高的问题；本发明的多功能雷达认知干扰决策方法，首先将干扰决策问题建模为带收益的马尔可夫决策过程，同时建立基于航迹的多功能雷达威胁评估模型，以威胁评估结果为依据得到干扰决策的收益函数。最后，利用强化学习算法Q-Learning对该问题进行求解，得到最优干扰策略。
