ABSTRACT:
A millimeter wave image processor, capable of performing imaging by matching and filtering while considering a spherical wave on an antenna face in a near field, is provided. The processor includes: a T-antenna which receives a radio wave emitted by a target; an A/D converter which A/D converts signals received by the T-antenna; a correlation processing unit which performs correlation processing to a combination of signals of a horizontal conversion output and a vertical conversion output among A/D converted data; and an imaging processor which correlates a reference function in which a received signal is generated theoretically on an assumption that the target is at a position of a focused distance and a received signal of a spherical wave received by the T-antenna for each pixel in the field of view to thereby create an image of the target.
