摘要
在目标回波仿真原理的基础上 ,给出了一种新颖的脉冲多普勒雷达目标回波视频脉冲仿真电路。通过计数分频和计数延时技术 ,该电路获得了大范围可变的脉冲重复频率和高精度的脉冲时延 ,能对距离不断变化的动目标进行实时模拟。给出了电路的结构框图 。
Based on the principle of target echo simulation, a video pulse simulator on PD radar target echo is presented in this paper The variable PRF and the precise time delay to the pulses are available through the counters, and the changing distance of targets can be simulated in real time The structure diagrams and the principle of the circuits are also illustrated in the paper
