新型雷达动态目标模拟器的研究

Research on the New Type of Radar Dynamic Target Simulator

讨论了一款新型的雷达动态目标模拟器。该模拟器可对飞行目标的距离和速度进行模拟 ,以改变信号源的载频来模拟目标的多普勒频移 ,通过对雷达视频脉冲的可编程延时来模拟目标的距离变化。可编程脉冲延时是由EPLD来实现的。该模拟器具有高稳定、高精度、操作简单。

A new type of radar dynamic target simulator based on EPLD is discussed in this paper. The simulator can simulate the distance and speed of the flight target. It simulates the target's speed by changing the carrier frequency of the signal generator and distance by programming the delay of radar video pulse. The programmable pulse delay is implemented by EPLD. The simulator has the feature of high stability, high precision, easy operation and broad practicability.
