一种通用型PD雷达目标模拟器

A Common PD Radar Target Analogue

介绍一种雷达目标模拟器，用两台高稳定度且具有外时基功能的频率合成微波信号源分别作为回波信号及杂波信号载波源，其外时基口作为雷达相参信号输入口。视频脉冲延时及多普勒频移都可由计算机控制，模拟雷达与目标之间的不同距离及相对速度，模拟器收发共用一付天线，天线安装在可旋转机构上，用以检测雷达角跟踪能力。

In this paper, a radar target analogue is introduced.Two microwave synthesized source which haveexternal time base function are used as radar return signal and clutter sources.Their external time base is used radar coherence signal input.Video pulse delay and doppler shift can be controled by computer in order to modullate the relative distance and velocity between the radar and a target.In this analogue .an antenna which is commonly used by the transmitter and the receiver is installed at a rotary machine for checking the angle tracking function of a radar.
