多输入多输出(MIMO)雷达是一种新体制雷达,信号处理是其核心技术之一。为了实现MIMO雷达从理论研究到工程实现的跨越,针对MIMO雷达技术研究缺乏平台支撑的问题,研发了MIMO雷达信号处理半实物仿真系统。文中提出了系统总体设计方案,介绍了系统的功能和组成,给出了关键技术的实现路线,包括硬件和软件的设计方法,阐述了系统的工作模式。该系统可以很好地验证MIMO雷达信号处理方法和相关算法的正确性。
Multiple-input multiple-output (MIMO) radar is a new system of radar, signal processing is one of its core technologies. In order to realize the leapfrogging of MIMO radar from theoretical research to engineering realization, aiming at the lack of platform support for MIMO radar technology, a semi-physical simulation system of MIMO radar signal processing was developed. In this paper, the overall design of the system is presented. The function and composition of the system are introduced. The implementation of key technologies is given, including the design method of hardware and software, and the working mode of the system. The system can well verify the correctness of the MIMO radar signal processing method and related algorithms.
