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。介绍了动态距离模拟基本原理、系统自修正基本原理。设计了一套集激光接收、延迟控制、高精度信号延迟、激光器、修正光纤、平衡探测器等单元于一体的动态距离模拟系统,该系统能够模拟出高精度的动态距离信息,并具备系统自修正能力,解决了动态距离模拟器的仪器参数漂移问题。动态距离模拟器的精度检测实验、动态距离模拟器与星载激光测距体制设备实际工作试验,共同证明了该系统的精度、性能稳定性可以满足目前国内绝大多数星载激光测距体制设备地面检测的需求。For the performance test of a satellite-based laser ranging system on ground, high-precision, stable and ad- justable simulation distance light pulse are needed, thus the adjustable distance simulation technology has been devel- oped. The basic principles of adjustable distance simulator and system＇s self-correction are introduced in this paper. An adjustable distance simulation system was designed which consists of laser receiving, delay control, high-precision signal delay,lasers, correction fiber and balanced amplified photodetector etc. Meanwhile a self-correction system was designed to overcome the parameter drift of the adjustable distance simulator. The precision and stability of this simu- lator satisfy the demands of most domestic satellite-based laser ranging sensors＇ performance tests. That has been prov- en by experiments and practical application.
