Abstract :
A theory has been developed which accounts for the empirically known facts of maximum entropy method´s (MEM) sensitivity to the RF phase difference between targets, the effects of averaging with respect to variations of the phase difference, and the effect of noise. Of importance is the discovery from the theory that the effect of noise can be markedly reduced beyond what was previously believed to be the resolution limit suggested by Gabriel´s data. Experimental evidence indicates a 7-15-dB improvement.
