Minimum-relative-entropy method—solution to missing short-baseline problem

Minimum-relative-entropy method (MREM) has been presented as a solution to the missing short-baseline problem in the synthesis observations. It is shown that a measure of distance between the prior model and the image in the plane of pixel brightness is an adequate measure of relative entropy. The method has been further extended for polarization observations and the potential of the method against the conventional MEM has been demonstrated by simulated examples.
