Abstract:	The minimum-relative-entropy method (MREM) is proposed as a solution to the missing short-baseline problem in radio 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 is further extended for polarization observations and the potential of the method against the conventional MEM is demonstrated by simulated examples.
