动目标侦察雷达模拟训练器回波形成单元的设计与实现

Design and Realization of Echo Unit of Moving-target Indication Radar Simulator

通过分析活动目标侦察雷达动目标显示的基本工作原理,得出对活动目标回波信号的模拟必须包含三种信息:幅度信息、频域信息、时域信息。根据这些条件,对活动目标侦察校射雷达模拟器的回波形成单元进行了基本设计。在组成框图设计的基础上,结合实际经验,设计并实现形成活动目标回波信号的基本电路。

This paper has introduced the working principles of moving-target indication radar. So we get the conclusion that if we want to simulate the signals of moving-target indication radar echo, we should get three kinds of information： range information, frequency information and time information. According to these conditions, we have designed the basic block diagram of the echo unit of moving-target indication radar simulator. With the design of block diagram and our practical experiences, we design and realize the circuits of echo signals of moving-target radar indication.
