摘　　要：主动成像激光雷达由系统本身提供照明,不必再依赖太阳角,可全天候工作,具有远距离、高分辨率、三维成像能力。特别是具有目标探测、识别和辨识等方面的超强能力,战场上在预警、信息获取、目标监视和侦查方面有很重要的应用。介绍了两种不同体制主动成像激光雷达:一种是采用相干成像合成孔径红外激光雷达,另一种是采用孔径平面散斑强度信息成像激光雷达。阐述了两种不同体制主动成像激光雷达的原理、特点和研究现状,并对其关键技术和应用前景进行了简要的分析。Active imaging ladar, because they provide their own illumination, are capable of operating 24 hours a day and are not dependent upon the angle of the sun. They can provide ultra-high resolution and three-dimensional imaging at long range. These capabilities would be promising in target detection and remote sensing and mapping. These capabilities would improve Battlefield Awareness (BA) and provide persistent Intelligence, Surveillance, and Reconnaissance (ISR) to perform target detection, recognition, and ...
