摘　　要：介绍了相干激光雷达对目标探测的技术优点和现状,阐述了基于相干探测技术构建的激光雷达的主要组成,并给出了整个系统的工作流程。文中基于1.5μm光纤光学技术搭建了相干激光雷达系统。通过搭建的系统进行了外场试验,获得了外场目标的成像图和不同汽车引擎振动产生的微多普勒谱特征图。通过试验证明了相干激光雷达系统可以在目标自动侦察识别方面发挥重要作用。The advantage and current situation of the coherent lidar in object detecting are introduced in the paper.The main constitutes and workflow of lidar based on the coherent detecting technology are given. The coherent lidar system is constructed based on 1. 5 μm fiber optical technology. The outfield experiments were carried out by using the system. The images of the objects in outfield and the micro-Doppler characteristic images produced by the car＇s motor quivering were obtained by using this system. The experiments prove the importance of the coherent lidar system in objects reconnoitering and identifying.
