摘要
介绍基于直接数字频率合成(Direct Digital Synthesis,DDS)技术的雷达中频回波信号模拟器的设计与实现方案,该模拟器可以模拟生成脉冲雷达接收机内下变频后的中频回波信号,并能灵活地对回波的目标特性进行控制,具有良好的可编程能力。
A project of Radar intermediate in this paper. The simulator can simulate frequency echo simulator based on Direct Digital Synthesis is the IF echo signal of the pulse radar receivers. It can also target characteristic of the echo neatly and has a good programmability.
