| Abstract: | In this paper,the point spread function (PSF) of incoherent imaging system is introduced into satellite laser ranging system.The base expressions of the PSF of satellite used for laser ranging are deduced in detail.The PSF of Lageos and ERS satellite as well as the intensity distribution of the pulse acted by the PSF are calculated.The results are excellent. |
