摘　　要：对于在用雷达系统,天线方向图关系到雷达系统对被测目标的快速捕获、正确跟踪以及雷达作用范围等,所以天线方向图测量尤为重要。传统的天线方向图测量通常在微波暗室中进行,需要专用的天线转台测试系统,还要求被测天线提供馈线接口;而在用雷达通常将天线、发射机、接收机等进行一体化封装,为确保性能,不宜将天线单独拆卸,从而使得天线方向图测量难以实施。将某型精密测量雷达的发射天线和发射机、接收天线和整个接收机与终端分别作为一个整体,实现了天线及其相关系统的整体方向图在线测量,通过对测量不确定度的评定表明,该测量方法满足使用要求。In the radar system,the antenna pattern is related to the objectives to be measured and rapid capture of correct tracking as well as radar range,so the antenna pattern measurement is particularly important.Traditional antenna pattern measurement is usually done in microwave dark room,need special antenna test turntable system,antenna under test are also required to provide feeder interface,and in the integration using radar antenna of a transmitter to a receiver,encapsulation,in order to ensure performance,should not be separate remove the antenna,so as to make the antenna pattern measurement is difficult to implement.This paper will be of a certain precision measurement radar transmitting antenna and a transmitter antenna and the receiver respectively with a terminal as a whole realized the antenna and its related online measuring system of the whole pattern,through to the measurement uncertainty evaluation showed that this method meets the requirement.
