Abstract

This paper describes a simulator we have developed to model speckle imaging and resconstruction of astronomical objects. The simulator was designed as a tool in the development of new signal and image processing techniques for our high resolution imaging research. It has been found to accurately replicate the speckle imaging process, and can be used to predict experimental results under various environmental conditions. The simulator is described in detail, including the modeling of atmospheric turbulence effects, the generation of speckle images, and the simulation of the telescope and image detection processes.
