设计了一种基于激光图像跟踪的激光雷达系统来实现目标的跟踪测量。该系统通过激光光束二维扫描，形成包含距离和角度信息的三维图像，由测量视场内运动目标的几何中心与视场中心的角度偏差获得脱靶量，利用脱靶量驱动伺服机构使目标几何中心处于雷达扫描视场中心，从而实现目标的实时跟踪，并输出目标距离和角度信息。实测结果表明：采用设计的激光雷达系统对距离900 m的目标进行测量，测距精度优于025 m，角跟踪精度优于007°，角跟踪能力优于12(°)/s，实现了快速捕获目标、高精度跟踪测量和系统小型化等既定目标。

In order to realize tracking and measurement for targets, a laser radar system based on image tracking is designed. The system produces a three dimension image with distance and angle information by a two dimension mechanically scanning of laser beam. It uses the miss distance, difference of azimuth and the pitch between the center of moving target and the field of view of scanning to drive the servo mechanism to keep the target in the center of sight to track the target in real time. At the same time, the valuable information of distance and angle is exported. Through a series of experiments on the system, it shows that for the target at the distance of 900 m, the accuracies of distance measuring and angle tracking are better than 025 m and 007°, respectively, and the ability of tracking is better than 12(°)/s. The system achieves the system miniaturization, fast acquisition targets, high accuracy measurement and tracking.
