| 摘 要： | 针对脉冲激光雷达系统,通过对激光脉冲重叠方式的分析,确定了采用"五点式"重叠方式进行扫描。针对这种扫描方式,分析了方位和俯仰两个方向的扫描光束角步长,确定了对于确定探测空域的最短扫描时间,推导了反射镜在方位和俯仰两个方向的扫描速度以及两者之间的定量关系,给出了脉冲激光雷达扫描器方位扫描速度和俯仰扫描速度设计的理论依据。最后分析了激光器和机械扫描系统所引起的系统误差,并给出了解决方法。

| Abstract: | In this paper, the overlap mode of laser impulse is analyzed for laser impulse radar. The special scanning mode called Five-Points mode is used for the laser impulse radar. According to the scanning model, the steps of azimuth and pitching scanning angles are analyzed and the best scanning times is given. To provide the theory guidelines of laser impulse radar scanning system design, the reflector scanning speeds in azimuth and pitching angles are derived and the relation between them is given. Finally, the scanning system errors caused by laser and machine system are analyzed and the solutions are presented. |
