Abstract
A circumferential array of n transducers is used to image an object with resolution equal to that of an array over the entire bounded aperture. This is done by illuminating the object with m components of coherent wave energy, and coherently detecting the signal picked up by each of the n transducers for each of the m wave energy components to provide the coefficients of m complex numbers for each of the n transducers. Signal processing these coefficients, in the manner described in the disclosure, permits an image of the object to be displayed on a display device with resolution equal to that of an array filling the aperture.
