摘要
以激光距离多普勒成像雷达系统(LRDIR)能够提取空间目标激光散射信号特征,判断空间目标在轨运行姿态为应用背景,给出了激光距离多普勒成像激光雷达系统设计的一般原理,并指出系统重要组成部件,在信号检测过程中所起的作用。结合相关实际测量材料的试验数据和器件性能参数,分析系统性能和各种干扰噪声,并计算系统在探测单元和探测阵列两种情况下,信噪比随探测距离和接收器口径的变化规律,为具体工程应用提供可靠的依据。
According to Laser Range Doppler Imaging Radar （LRDIR） extracting the signature of laser scattering signal and judging all kinds of gestures and micro-motion of space targets on their orbits, the general design principle of LRDIR was given. And then, different crucial components were pointed out that were important operation in the course of detecting signal. Finally, the system performance and all kinds of possible noise were analyzed by the measured data of the actual material and apparatus parameters. The SNR changed with detecting distance and diameter of detecting receiver in detector unit and detector unit array was computed. The results provide credibility for engineering application
