The concept and principle of Synthetic Aperture Laser-Radar (SAL) are summarized. The influence of atmosphere on the transmission of Synthetic Aperture Lidar is analyzed. The effects of laser wavelength, vertical transfer height, horizontal transfer distance, visibility, radiation source platform Height and beam elevation on SAL transmission characteristics, the simulation results obtained a series of curves, the design of synthetic aperture lidar has some reference and guidance for the future in the SAL project to select the laser wavelength lays the foundation Theoretical basis.
