三维图像能准确反应目标的物理特征,提高目标识别的性能,但传统的光学三维成像技术受到扫描体制或阵元个数的限制,很难实现对运动目标的实时成像,针对这一问题,提出了一种将逆合成孔径技术、激光信号与干涉技术相结合的逆合成孔径三维成像激光雷达,给出了系统的初步设计方案,分析了成像的基本原理和实现方法,构建了模拟系统,进行了仿真分析,实验结果验证了该雷达系统的可行性和成像中的优势,最后讨论了系统实现过程中还需要解决的关键问题。 更多还原

【Abstract】 Three-dimensional Image can represent target′s physical characteristic well and improve target recognition capability,but conventional optical imaging radar is limited by the array units or scan system and can not realize the imaging of moving targets.This paper combines the inverse synthetic aperture technology,laser signal and interferometric technology to suggest a new radar system which is called Inverse Synthetic Aperture 3-D Imaging LADAR.It describes the initial design of the system,analy... 更多还原
