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0.15 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。
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 superior 0.15 m are proved by experiments,satisfing the demands of the performance test of all kinds of satellite-based laser ranging system equipment on earth by now.
