摘　　要：认知多输入多输出(multiple-input multiple-output,MIMO)雷达将认知技术与MIMO技术相结合,具备动态环境信息感知和自适应调节能力,受到雷达界的广泛关注。相比于传统雷达,认知MIMO雷达性能更优、适应性更强,是雷达迈向智能化发展的趋势,而发射波形的优化设计是实现雷达认知的关键,因而成为近年来学者研究的重点。首先介绍了认知MIMO雷达基本概念,分析了波形设计现状,然后在波形设计步骤的基础上,重点从优化准则和优化方法两方面总结了现有研究成果及特点,最后讨论了未来研究方向和需要解决的问题。Cognitive multiple-input multiple-output（MIMO）radar is a combination of cognitive technology and MIMO technology,it has the perceptive ability of dynamic environment information and the adaptive ability to adjust the waveform,which has been attracting much attention of researchers in the field of radar. Compared with traditional radar,cognitive MIMO radar has better performance and stronger adaptability,thus it is the trend of radar which develops toward the direction of intelligence.The technique of waveform design is the key to help radar realize cognitive function,so it has obtained much attention and been intensively studied in recent years. In this paper,basic concept of cognitive MIMO radar is introduced and current situation of waveform design is analyzed firstly,then based on the steps of waveform design,existing research results mainly from the perspective of optimization criterion and optimization method are summarized,finally future research directions and problems need to be solved are discussed and prospected.
