Title:
RADAR IMAGE PROCESSING DEVICE AND RADAR IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/187236
Kind Code:
A1
Abstract:
This radar image processing device (10) is configured to be provided with: a phase difference calculation unit (23) which calculates, for respective reflected signals that coexist in a single pixel, a phase difference which is the difference in phases with respect to mutually different radio wave receiving locations; and a rotation quantity calculation unit (31) for calculating, from the respective phase differences, phase rotation quantities of a plurality of pixels encompassed in a second radar image, wherein a difference calculation unit (32) rotates the phases of the plurality of pixels encompassed in the second image on the basis of the respective rotation quantities, and then calculates the difference between the pixel values of respective pixels located at corresponding positions between a group of pixels encompassed in the first radar image and a group of phase-rotated pixels encompassed in the second radar image.
