摘　　要：认知雷达是雷达领域的一个新的研究热点,它最重要的特点是先获取目标及周围环境的特性,根据回波特征改变雷达的工作模式,变换发射波形,调整优化雷达系统资源,使雷达性能最优化。介绍了认知雷达系统的架构,设计了两种工作模式,通过发射一个搜索波束和两个跟踪波束,实现了搜索跟踪一体化的工作方式。Cognitive radar is a newhot researching field of radar technology currently.The most important characteristic of the radar is to switch the operating mode of radar according to the echo feature after fetching the characteristics of the target and environment,and change the transmitted signal waveform to optimize the allocation of system resources andmake overall performance of the radar system to the best.This paper introduces the architecture of cognitive radar system,designs two operating modes,realizes the operating mode of searching and tracking integration through transmitting one searching beam and two tracking beams.
