| 摘 要： | 有源相控阵天线需要对接收和发射两种状态的天线方向图进行测试。现有天线测试远场只能进行接收态的方向图测试,介绍了在远场进行发射态方向图测试的一种简易方法。利用远场的测试转台和发射喇叭,使用频谱分析仪接收有源相控阵天线发射的数据,编制测试软件采集处理数据,即能实现有源相控阵天线发射方向图的测试。该测试方法简单易行。

| Abstract: | It is necessary to test antenna beam pattern in transmitting and receiving mode of the active phased array antenna.The existing far field test for antenna is to test antenna beam pattern in receiving mode.In this paper,an easy way to test transmit beam pattern was presented.In the test,testing pedestal for radar antenna and transmitting horn of the far field test were used.And then the spectrum analyzer received the data which the active phased array antenna had transmitted.Test software was developed and installed in the central master computer to collect data and test transmit beam pattern of active phased array antenna in real time.It proves that the test method is simple and easy to carry out. |
