摘　　要：成像激光雷达作为一种主动成像手段,具有在低照度、复杂背景条件下获取高分辨率远距离景物三维图像的能力,作为任务载荷应用于无人机系统领域已成为一种必然趋势,前景十分广阔。对成像激光雷达技术体制进行总结归类并对其国内外研究进展进行了技术分析,并在此基础上,结合无人机载环境特点,针对典型应用场景,综合考虑成像距离、成像分辨率、成像范围和成像速度(帧频)等多方面因素,从总体上探讨并提出无人机载成像激光雷达的一般结构形式、典型技术方案选择和平台适应性要求,以期对相关技术研究和设备研制起到一定参考作用。Imaging lidars, operating at an active imaging approach, are capable of obtaining high resolution 3D images of objects at far distance even under low illuminance and complicated background conditions, thus it has been an inevitable trend for imaging lidars to be used as mission payloads in the UAS field with extensive application prospects. The types of imaging lidars were summarized and categorized, with technical analysis carried out on relevant research progresses both at home and abroad. On this basis, discussions are made in the view of system design and general structural formats, typical technical architectural options and platform suitability requirements for the UAV-borne imaging lidars were put forward, in combining the features of the UAV-borne environment and in association with comprehensive considerations of the factors as imaging distance, imaging resolution, imaging range and imaging speed （or frame rate） related to typical application situations, with an expectation to provide reference for relevant technology research and equipment development.
