【摘要】 为了验证远程激光雷达系统的关键技术,提出了一种基于Nd:YAG固体激光器的激光雷达试验系统。试验系统由光学收发子系统、伺服子系统、信号处理子系统组成,利用电荷耦合器件进行引导,采用双探测器型复合轴同步控制技术实现对目标的精密跟踪,采用数字域的信号处理方法提升系统的探测精度。最后分析了系统对不同反射截面积目标的探测距离,分析结果表明,在1级大气条件下,系统对1m~2目标的探测距离达到22km。更多还原

【Abstract】 In order to testing the key technologies of long-range Ladar, the experimental system is proposed based on the Nd:YAG laser. The system is combined with optical sub-system, servo sub-system and signal process sub-system, and is directed by charge-coupled device(CCD) when working. Composite axis control based on two detectors is adopted to realize the precise tracking of the target. Meanwhile, in order to increasing the detection precise, the laser signal is processed in digital domain. At last, the detection range of the system is analyzed versus different laser cross section targets(LCS). The result shows that if the LCS is 1m~2 and the atmosphere is first order, the detection range of the system is 22 km.更多还原
