In this paper we derive expressions which show that, from the point of view of reaching minimum in the rms error of phase estimate, the spatial distribution of sounding signal in the target plane as a finite function different from zero only within the target contour is optimal. This situation allows further development of the technique of active image reconstruction and stimulates euristic approach to synthesis of reconstruction algorithms in contrast to regular one since it does not impose any restrictions on sounding signals.
