脉冲式激光测距体制设备动态距离模拟器的研究设计

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0.15 m,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。

Design of a adjustable distance simulator for pulsed laser ranging system equipment

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 are 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 was designed to simulate distance. The minimum simulation distance of the adjustable distance simulator achieving 15m, the accuracy superior 0.15m were proved by experiments, satisfing the demands of the performance test of all kinds of satellite-based laser ranging system equipment on earth by now.
