摘　　要：针对传统米波天线尺寸庞大、机动性差的问题,文中利用干涉仪测角原理,提出了一种可以应用于可全方位同时探测的米波雷达天线及相应的测角算法,该天线尺寸小、结构简单,测角算法具有测角精度高、算法简单的优点,设计了一种基于此算法的信号处理流程,给出了在不同信噪比时测角误差的仿真结果,仿真结果表明了该算法的有效性。Based on the principle of interferometer angle measurement, an omnidirectional meter-wave radar antenna and its related angle measurement algorithms are provided in this paper. Unlike traditional large and poor maneuverable antennas, the new antenna had small size and simple structure, and the algorithms were simple and high accurate. In addition, the paper designed the algorithms＂ signal pro- cessing flow, and presented the simulation results of angle error on different SNRs, which proved the algorithms＂ effectiveness.
