认知雷达抗干扰中的博弈论分析综述

雷达对抗的核心研究内容主要是干扰策略与抗干扰策略之间的对抗博弈,其作为电子战研究领域的热点一直备受学者们关注.该文综述了学者们利用合作与非合作博弈方法来分析雷达在进行目标探测和干扰抑制时所使用的策略,主要通过不同体制的雷达利用认知技术感知和学习外界复杂的电磁环境,合理地分配发射功率、控制编码序列、设计波形、研究检测和跟踪方法以及分配雷达通信资源等.这样雷达既节约发射所消耗的功率,又可以自适应地搜索和跟踪目标而不被敌方所发现,从而使雷达在复杂多变的现代战场环境中达到自身最优的性能.最后,对认知雷达抗干扰中的博弈论分析研究进行总结和展望,并指出了一些博弈论在认知雷达抗干扰策略应用中所面临的潜在问题和挑战.

A Review of Game Theory Analysis in Cognitive Radar Anti-jamming

The core research contents of radar countermeasures are the games of countermeasures between jamming strategies and anti-jamming strategies. As a hotspot in the field of electronic warfare, radar countermeasures have been paid much attention by scholars. This paper summarizes that the scholars employ the cooperative and non-cooperative game methods to analyze the radar against jamming while probing targets. Different radar systems make use of cognitive techniques perceive and learn the complex electromagnetic environment, and reasonably allocate transmitting power, control coding sequence, design waveform, investigate detection and tracking methods and allocate resources of radar communication etc. In this way, radar can not only reduce power consumption, but also search and track the target without being detected by the enemy. Thus, radar can achieve its optimal performance in the complex and changeable modern battlefield environment. Finally, game theory in cognitive radar anti-jamming is summarized and prospected, and it also points out some potential problems and challenges of game theory in cognitive radar anti-jamming.
