脉冲式激光测距体制设备动态距离模拟器的研究设计

摘要

地面检测星载激光测距体制设备的性能时,需要提供稳定且随机可调的高精度仿真距离光脉冲,于是提出了动态距离模拟技术.设计了一套集激光接收、延迟控制、高精度信号延迟、激光器等单元于一体的动态距离模拟系统,模拟高精度的动态距离信息.实验证明,该系统的最小模拟距离达到15 m,模拟精度优于0.15m,可以满足目前各种星载激光测距体制设备地面检测的要求.%In the performance test of the satellite-based laser ranging system equipment on earth, optical pulse for simulating distance with high -precision, stable and adjustable were needed, then the adjustable distance simulation technology was developed. A adjustable distance simulation system consisting of laser receiving, delay control, high-precision signal delay and laser emitting units is designed to simulate distance. The minimum simulation distance of the adjustable distance simulator achiev 15 m, the accuracy superior0. 15 m are proved by experiments, salisfing the demands of the performance test of all kinds of satellite-based lager ranging system equipment on earth by now.
