基于FIFO的目标距离脉冲模拟电路

A Radar Range Simulator Based on FIFO

介绍一种目标距离脉冲模拟电路。与其它常用的目标脉冲回波模拟电路相比,它具有与雷达发射脉冲频率无关、自动适应雷达模拟发射脉冲频率的变化、适应高重复频率和易于使用EPLD实现等优点。给出相应电路的结构及提高精度的方法,该方法在雷达模拟器中的应用效果良好。

A new kind of radar target range pulse simulator is presented in this paper. Compared with other the same kind of simulator, this simulator has a independence on the pulse repeat frequency (PRF), an adaptivity to the change of PRF and the high PRF, and a capability to use EPLD etc. The structure of the circuit and mehtod of improving accuracy are also given. It is shown that the simulator has a good performance in a real simulator.
