ABSTRACT:
A system for the model-based compression of speckle images in which the pulse characteristics of the known coherent imaging system which generated the speckle image to be compressed are used together with a scatterer image model to modify that scatterer image to contain impulse information such that when the impulse information is convolved with the pulse, the speckle image is reproduced. The modified scatterer image is compressed and outputted together with the pulse characteristics so that the speckle image can be reproduced.
