Abstract

Abstract

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.
