| Abstract: | The effect factors of LLL imaging,which include the change of illumination,meteorology and the characteristics of ICCD,were studied.The mathematical models of LLL scene simulation were established including ground reflectance model,atmosphere transmission model,ICCD model and noise model.Based on the effect of ground spectral reflectance acting on LLL image contrast,an LLL image simulation scheme was proposed.At last,the LLL scene simulation system using the computing kernel of LOWTRAN7 was developed.The simulating result shows this scheme is available. |
