合成孔径激光雷达大气传输特性研究

Research on Synthetic Aperture Laser-radar's Atmospheric Transmission Characteristics

概述了合成孔径激光雷达(Synthetic Aperture Laser-radar,SAL)的概念和原理,分析了大气对合成孔径激光雷达传输的影响,研究了激光波长、垂直传输高度、水平传输距离、能见度、辐射源平台高度和波束仰角等对SAL的传输影响特性,通过仿真研究得出了一系列关系曲线,对合成孔径激光雷达的设计具有一定的借鉴和指导意义,为将来在SAL工程研制上选择激光波长奠定了理论基础。

The paper discusses the conception and theories of Synthetic Aperture Laser-radar( SAL),analyses the influence of atmosphere on the SAL's laser transmission,and studies the influence of the laser wavelength,vertical transmission altitude,horizontal transmission distance,visibility,laser height and beam elevation on the SAL,finally by lots of the simulation,a series of relation curves are educed,which will be used as reference and guidance on the SAL's design and lay a theoretical foundation for the selection of the laser wavelength in the engineering development of SAL.
