摘　　要：星载和机载远距离目标的高分辨成像一直是科研人员不断追求的目标,为了突破远距离光学系统孔径衍射受限的问题,国内外先后发展了多种激光成像雷达技术。着重介绍了基于"点发射、面照射、点接收"工作模式来实现远距离目标高分辨成像的四种激光成像雷达基本原理,给出了这几种类型激光成像雷达的国内外实验和工程化进展程度,并进行了相应的比较。Techniques of spaceborne and airborne high-resolution imaging for long-range target are always the goals of researchers. To break through the diffraction limitation of optical aperture system, several imaging lidar techniques are developed at home and abroad. Four types of imaging lidar principle based on ＂point emitting, area irradiating, point receiving＂ are given. The corresponding experimental and engineering achievements are introduced and compared.
