摘要
在空间交会激光雷达关键部分捕获、瞄准、跟踪(APT)系统中,对天线扫描捕获技术进行了理论分析和模拟实验研究。建立了光学天线扫描捕获的理论模型,在此基础上对影响系统捕获性能的各主要参量之间的关系进行了数值仿真分析。将分行式螺旋扫描引入到激光雷达APT系统中,建立了数学模型并进行了数值仿真。根据仿真结果提出并优化了螺旋扫描方式,取得了良好的效果。
APT is the initial part of the Rendezvous and Docking laser radar system , in which the acquisition with antenna scanning in laser radar was studied through both theory and simulation.A theoretical model for optics acquisition was presented in this paper, and some parameters that influence the system of acquisition were analyzed.The square spiral scan was brought to the laser radar APT system, and a mathematical model was set up, while simulation was completed.From the simulation results the spiral scan is optimized.
