认知雷达是将雷达参数与周围环境因素有机结合的一种新型雷达体制,它基于交互自主学习的方式来感知周围环境,通过调整信号发射、接收及信号处理方式来提高雷达系统的整体性能指标。经过近二十年的研究,认知雷达及其关键技术得到了飞速发展。文中综合大量认知雷达文献资料,对认知雷达结构和组成给出了相对全面的对比与分析,并从硬件技术、波形优化、检测识别与跟踪、抗干扰及组网等关键技术方面对其研究现状进行了详细分析,最后对认知雷达的发展方向进行了展望。

Cognitive radar is a new type of radar system which combines radar parameters and environmental factors. It perceives the surrounding environment based on interactive autonomous learning, and improves the overall performance of radar system by adjusting signal transmission, reception and signal processing methods. After nearly 20 years of research, cognitive radar and its key technologies have been developed rapidly. This paper comprehensively studies a large number of cognitive radar literature, gives a relatively comprehensive comparison and analysis of the structure and composition of cognitive radar, and makes a detailed analysis of its research status from the aspects of hardware technology, waveform optimization, detection, recognition, tracking, anti-jamming, networking and other key technologies. Finally, the development direction of cognitive radar is prospected.
