摘要

本文论述方位机扫、俯仰相控电扫舰载三坐标雷达天线阵面电子稳定方法。通过分析计算证明了采用电子稳定方式的三坐标雷达在大部分情况下不会出现漏空域现象，同时还给出了天线电子稳定三坐标雷达设计时几个关键参数的计算方法：俯仰所需最大相控角度计算方法，俯仰波束指向水平面的相控角度计算方法，俯仰方向电子扫描所需波位数计算方法，雷达俯仰角度计算方法等。%This paper deals with the electronic stability method for antenna array of shipborne 3D radar with mechanical scanning in azimuth and electronic scanning in elevation. Through analysis and calculation, it is proved that airspace missing in 3D radar using electronic stability method will not occur in most situations. The computing methods for several key parameters are provided in designing the 3D radar with electronic stability antenna, including computation of maximum phased-array angle in elevation, computation of phased-array angle for beam pointing horizontal plane in elevation, computation of beam digital required by electronic scanning in elevation, computation of elevation angle for radar, etc.il.
