Abstract

PURPOSE: To save the capacity of a memory by about a half in an object section video converter, by utilizing that the columnward address of a data to be given an access to a waveform memory is symmetrical to a scanning point corresponding to visualization point in an address table.
CONSTITUTION: Received signals at scanning points containing information at a point (a) intended for visualization have respective phase delays only corresponding to a distance between the scanning points and the point (a) and the locus of the phase delays present a hyperbola whose vertex is point (a) as illustrated. Then, to reproduce the point (a) in the drawing, received signals at the scanning points pertaining to the point (a) are added up along a phase locus in a range of the length L of an synthetic aperture. An object section visualizer thus obtained utilizes that a column address with respect to the scanning points of a data necessary for reproduction of a point as address table is symmetrical to the a scanning point corresponding to a visualization line containing a point as a phase history line is symmetrical to the visualization line.
