介绍了一种基于PC+ARM+DSP+DDS体系结构的通用雷达中频信号模拟器。该系统能够模拟多种体制的雷达中频信号,而且不同信号间切换方便、使用灵活。介绍了该系统的硬件设计和在模拟相参脉冲雷达动目标信号中的应用。
A universal radar IF simulator based on PC + ARM + DSP + DDS architecture is introduced. The system can simulate a variety of systems of radar IF signal, and easy to switch between different signals, the use of flexible. The hardware design of the system and the application in the simulation of coherent pulse radar moving target signal are introduced.
