认知雷达通过模仿人类认知功能实现智能化,在与环境交互作用下自适应调整雷达收发功能以实现性能提升。文中首先分析了认知雷达的研究背景,从认知的基本概念入手,介绍人类认知特性与认知雷达系统的映射关系;然后,阐述了认知雷达系统原理,介绍认知雷达系统中知觉动作回路结构,并探讨了认知雷达的关键技术及其发展状况;最后,对我国认知雷达的发展提供一些展望。
Cognitive radar is intelligent through imitating human cognitive function, and adaptively adjusts the function of transmitting and receiving the radar under the interaction with the environment to achieve performance improvement. Firstly, the research background of cognitive radar is analyzed, starting with the basic concept of cognition, the mapping relationship between human cognitive characteristics and cognitive radar system is introduced. Then, the principle of cognitive radar system is introduced, and the perception Action circuit structure, and discusses the key technologies of cognitive radar and its development; Finally, some prospects for the development of China’s cognitive radar are provided.
