摘要
合成孔径激光雷达(SAL)能够突破激光的衍射限制, 满足对远距离目标和场景进行高精度实时成像的需求。从SAL理论和实验进展两方面, 详细总结分析了SAL的国内外发展现状。在此基础上, 总结和分析了实现SAL实际应用, 还需深入研究的几个关键技术: 激光光源、发射信号波形、探测体制、激光传输特性和目标反射特性、成像算法和运动补偿等, 为进行SAL的深入研究和实用化奠定基础。
Abstract
Synthetic aperture ladar (SAL) breaks through the diffraction restrict of laser, which is able to afford the need of high precision and real time imaging for the remote targets and scenes. The development situation of SAL at home and abroad is analyzed in detail, through two aspects of theoretical status and experimental progress. On this basis, the key technologies such as SAL laser source, emission signal waveform, laser transmission characteristics and target reflection characteristics, imaging algorithm and motion compensation are summarized and analyzed. It lays the foundation for further study and practical application of SAL.
