介绍一种基于PCI总线和DDS技术的通用雷达中频回波模拟器。该系统能够模拟多种体制的雷达中频回波,回波脉内信息更加丰富,模拟精度更高。介绍该系统的硬件设计,给出逆变换法求解回波振幅的方法,并对系统工作性能作简要分析。

This paper introduces a kind of general IF radar echo simulator based on PCI.bus and DDS technique. The simulator can generate kinds of IF radar echoes which contain much information and have high accuracy. The paper describes the hardware configuration of the simulator and a method to compute the echo amplitude by inverse transform, and also makes a simple analysis of its performances.
