摘　　要：在侦察领域或通信领域,在特殊平台的载荷按照空间限制下,面对具备良好的定向波束覆盖、低截获率、高增益等要求,存在一些特殊的天线设计需求,如透镜多波束天线、相控阵天线等,其中相控阵天线应用较为广泛,相较相控阵天线,需设计透镜多波束天线的测角算法,解决波束对准问题,使得透镜多波束天线在通信、侦察领域广泛推广。文中结合比幅法,采用了直接与迭代法相结合的方式,介绍了多波束天线测角原理,给出了测角流程、测角算法设计、角度信息转换处理的详细步骤。In the field of reconnaissance or communication,under the spatial limitations of special platforms,there are some special antenna design requirements for payloads with good directional beam coverage,low interception rate,high gain,etc.,such as lens multibeam antennas,phased array antennas,etc.Among them,phased array antennas are widely used.Compared with phased array antennas,it is necessary to design angle measurement algorithms for lens multibeam antennas to solve beam alignment problems,so that lens multibeam antennas can be widely promoted in the fields of communication and reconnaissance.This paper combines the amplitude comparison method with the iterative method,introduces the principle of multi beam antenna angle measurement,and provides detailed steps for angle measurement process,angle measurement algorithm design,and angle information conversion processing.
