中文摘要： 运动目标的振动特征体现了其精细属性，具有重要军事和民用价值，在目标探测与识别领域受到广泛关注。相干激光雷达遥感探测由于其测量精度高、抗干扰能力强和能远距离无损探测等优点，特别适合遥感探测目标的振动特征信息。 当前对目标振动的激光探测多偏重于近距离测量，对面向远距离目标的遥感探测机理、目标振动对回波调制模型、复杂运动目标振动回波相位检测和解算等的研究尚不够深入。本项目将结合相干激光雷达体系结构特点，展开目标振动相干激光遥感探测方法研究，主要内容包括：目标振动相干激光遥感探测模式、面向相干激光遥感探测的典型目标振动建模、回波相位有效检测和目标振动解算方法等一系列研究，并通过仿真和实验来验证模型和算法的正确性。本项目通过研究，给出面向相干激光探测的目标振动遥感测量理论和算法，拓展相干激光探测在振动遥感测量领域中的应用基础，用于支撑基于相干激光遥感探测的目标振动特征识别，及进一步的目标识别技术发展

英文摘要： Vibration features of moving targets can reflect their detailed characteristics, which have important military and civil values. This have been paid close attention to fields of target detection and identification. Coherent lidar is the preponderant method of target detection, because of its advantages such as high measurement accuracy, high anti-jamming capability and ability of long-distant non-destructive measurement, which is appropriate for detecting the vibration information of the target through remote sensing. Nowadays, researchers are placing particular emphasis on vibration laser measurement in close range, while researches such as remote sensing detection mechanism for long range target, modulate model of echoes of vibrating target, phase detection and vibration resolving of moving target are not deep enough. This project will develop some research in methods of target vibration measurement through coherent laser remote sensing, combining with the architecture characters of the coherent lidar. The project is composed of researches such as detect patterns of coherent laser remote sensing of target vibration, researches of modeling of vibration by typical targets facing coherent laser remote sensing, echo phase detection and resolving of target vibration. The validity of models and algorithms will be
