| 摘 要： | 空间交会激光雷达的任务是对空间动态目标的距离、速度以及方位等信息进行跟踪式测量。提出采用模拟插入脉冲计数法测距,幂函数族基于最小二乘曲线拟合微分法测速,四象限(QD)光斑定位法进行方位角测量。在Matlab/Simulink环境下,对采用该方法的脉冲激光雷达信息测量系统进行了计算机仿真,得到了与理论值相吻合的仿真结果。结果表明,采用该测量技术的脉冲激光雷达是可靠的。

| Abstract: | The space rendezvous lidar measuring system can be used to measure spatial dynamic object information of distance, speed and orientation. The method of counting pulse with analog intervene used to measure distance is put forward, and the method of differential coefficient of the fitting curve based on least-squares curve fitting that takes the exponential function is used to measure velocity, and the method of orientating facula by QD (Quadrant Detection) is selected to measure the orientation angles in the pulsed lidar measuring system. Computer simulation is implemented in the MATLAB/SIMULINK soft, and the simulation result coincides with theoretical analysis. As a result, the information measuring techniques of pulse lidar is reliable. |
