用条纹管作为接收端的激光成像雷达已经成为非扫描雷达中的重要部分,具有大视场、高帧频的优点,在军事上有着广泛的应用前景。用条纹管激光雷达四维成像实验平台对远距离目标进行了成像实验,给出条纹像和目标之间的对应关系,用多幅条纹像重构了目标的四维图像。实现了这种体制的激光雷达对远距离目标的成像。并且分析了狭缝、重叠率等参数对成像精度的影响。
The laser imaging radar with the streak tube as the receiving end has become an important part of the unscanned radar. It has the advantages of large field of view and high frame rate, and has a wide range of military applications. The imaging experiment of long-range target was carried out by using the imaging experiment platform of Lidar Lidar. The corresponding relation between fringe image and object was given. The multi-fringe image was used to reconstruct the four-dimensional image of target. Realized this system of laser radar for long-range target imaging. The influences of the parameters such as the slit and the overlap ratio on the imaging accuracy are also analyzed.
