Techniques have been developed which allow nearly all phases of the image forming process for turbulence degraded images to be computer simulated. The simulation includes generation of turbulence de-graded wavefronts, the degrading point spread function, and the sensor properties. Pre detection compensation of the wavefront and post detection compensation of the image can likewise be simulated. These simulation techniques have been used to determine fundamental limits of pre detection and post detection processing. Results of the application of these techniques to sun-illuminated objects will be presented in this paper.
