摘　　要：发射通道幅相特性是有源相控阵雷达的重要参数。为了能够简便快捷地对天线发射通道幅相特性进行准确测试,文章介绍了一种实用的有源相控阵雷达天线发射测试系统,重点论述了利用矢量网络分析仪,通过自制脉冲调制电路产生天线阵面所需要的激励信号,同时巧妙调整其中频带宽,从而实现了脉冲信号S参数的测量,最终辅以通信、仪器控制和软件技术构建有源相控阵雷达发射自动测试系统。该系统结构简单、实用,已应用于某些有源相控阵雷达近场测试。Amplitude and phase characteristics of transmitting channel are important parameters of active phased array radar. In order to test the amplitude and phase characteristics of antenna transmitting channel conveniently and quickly, a practical antenna transmitting test system for active phased array radar is introduced in this paper. In this paper, the vector network analyzer is used to generate the excitation signal needed by the antenna array through the self-made pulse modulation circuit. At the same time, the intermediate frequency bandwidth is adjusted skillfully so as to realize the measurement of S parameters of the pulse signal. Finally, the automatic test of the active phased array radar transmission is constructed by means of communication, instrument control and software technology. The system is simple and practical, and has been applied to the near field test of some active phased array radars.
