摘要
研究了MIMO雷达和相控阵的单脉冲测角技术,包括比幅法测角和比相法测角。比幅法测角采用等信号和差波束测角;比相法又分为实际阵列直接比相测角和虚拟阵列比相测角。在基本原理研究的基础上,采用MATLAB工具对几种测角方法进行了仿真,对比了MIMO雷达和传统相控阵雷达的测角精度,同时,也对几种测角方法的仿真结果和测角精度进行了比较和讨论。
MIMO radar is studied in the term of mono-pulse angle measuring technology, inclu-ding the amplitude comparison angle measurement and phase comparison angle measurement, which the amplitude comparison methed use the added and subtracted beam of equivalent signal and the phase comparison methed is divided into two methods, including the actual array direct phase measurement and the virtual array phase comparison. On the basis of the basic principles of research, the accuracy of the traditional phased array radar and MIMO radar angle measure-ment are compared with MATLAB simulation tools, and also simulative results and the accuracy of several angle measuring methods are compared and discussed.
