摘　　要：合成孔径激光雷达成像技术是一种能够突破光学系统衍射极限的主动光学成像技术,其概念来自工作在微波波段的合成孔径雷达,相比于合成孔径雷达,合成孔径激光雷达具有成像速度快、成像分辨率高以及能获取符合人眼感知的图像的优势,在远距离目标感知与识别中具有很高的潜在价值。本文从合成孔径激光雷达的工作原理出发,回顾和梳理了合成孔径激光雷达的主要关键技术的主要进展,包括合成孔径激光雷达的系统模型和基础理论、系统设计与架构、激光相位噪声抑制、运动补偿技术以及成像算法;同时对国内外重要的外场实验进展进行了总结。最后探讨了后续实现工程化所需面对的困难和挑战。Synthetic aperture ladar is an advanced active optical imaging technology that overcomes the diffraction limit of the traditional optical system.This technology is inspired by the working principles of synthetic aperture radar in the microwave band.Compared with synthetic aperture radar,synthetic aperture ladar has several advantages such as fast imaging speed,high resolution,and its images being similar to what the eye is used to seeing,thanks to its operation wavelength,which makes synthetic aperture ladar potentially valuable.This paper aims to provide a comprehensive review of the progress made in key technologies related to synthetic aperture ladar,including its system model and basic theory,system design and structures,laser phase noise suppression technology,motion compensation technologies,and imaging algorithms.Furthermore,some important outdoor experiments at home and abroad were summarized.At last,the difficulties and challenges for the subsequent implementation of engineering were discussed.
