一种雷达回波模拟器的研究与设计

Research and Design of a Radar Echo Simulator

为了满足各型雷达产品的测试要求,对雷达回波模拟器的要求越来越高,功能上也要求更加全面。本文阐述了一种新型雷达回波模拟器的原理及实现方法,着重介绍了目标回波功能实现原理、微波链路单元设计、基带单元设计等内容,并对系统的关键模块进行了分析。与传统雷达回波模拟器相比,增加了噪声干扰、假目标等设置。该模拟器技术先进、功能齐备、工作稳定可靠,已运用于实际。

In order to meet the test requirements of all kinds of radar products,the requirements of radar echo simulator are higher and higher,and the function is also more comprehensive. This paper describes the principle and realization method of a new type of radar echo simulator,emphatically introduces the realization principle of target echo,the design of microwave link unit,the design of baseband unit,and the key modules of the system are analyzed. Compared with traditional radar echo simulator,the simulator increases noise interference,false target and other settings. The simulator is advanced,fully functional and reliable,and has been used in practice.
