ABSTRACT:
Echo data relating to the distance away of reflective elements of an object surface is received by an array of receivers. A signal processing device receives the data and together with information as to the range of the object surface defines equitime loci of the object surface corresponding to the data. Image elements are displayed at positions in an image plane corresponding to the intersections of the equitime loci.
