摘　　要：雷达与通信系统一体化可以最大限度地利用雷达设备,使雷达的优良性能为通信服务.根据信号共享的原则,在保持成像雷达和通信各自功能实现的前提下,设计了一种基于随机频率步进调制的成像雷达通信一体化信号.该信号的设计方法是对发送的通信数据进行随机编码处理,然后将其调制到雷达载波的频点上发送出去,实现通信功能;而引入压缩感知理论后,采用这种信号仍能获得高分辨率的雷达图像,在一定功能上实现了成像雷达和通信的一体化.The radar and communication integration system can make full use of radars for communica- tion services. Aiming at keeping the performance of the radar and communication applications, and based on the principle of signal sharing, a scheme for integrated imaging radar and communication based on ran- dom stepped frequency modulation signal is proposed in this paper. In this scheme, the communication da- ta are random coded and modulated on the carrier frequency, and compressive sensing theory is adopted to realize radar imaging, which accomplishes the communication function without affecting the high resolution imaging radar performance.
