| Abstract: | In this paper,the reasons of forming the atmospheriacally blurred image and the principle of recoving it are discussed,and the physical model of blurred image based on atmospheriacal modulation transfer function is proposed.The predicting method about the atmospherical modulation transfer function is explained and the two basic terms(turbulence modulation transfer function and aerosol modulation transfer function)are stated.Then use the prediction of atmospherical modulation transfer function to recover the atmospherically blurred image.The simulation result shows that this method is effective. |
