本文介绍了我系雷达研究室研制的一种主要用中规模组件构成的动目标检测雷达的目标、杂波模拟器。它可以形成多种多卜勒频率的运动目标信号,以及云雨、地杂波和白噪声等多种杂波信号。这在鉴定有关雷达的动目标检测设备的性能时,是十分有用的。文中介绍了形成这些信号的有关原理和主要电路,并列出了有关信号的具体波形。 This paper introduces the target and clutter simulator of moving target detection radar, which is mainly composed of medium-scale components developed by our department. It can form a variety of Doppler frequency moving target signals, and a variety of clutter signals such as cloud rain, ground clutter and white noise. This is very useful in characterizing the performance of moving target detection equipment for radars. The article describes the formation of these signals on the principle and the main circuit, and lists the specific waveform of the signal.
