Document Type and Number:
WIPO Patent Application WO/2019/176016
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a radar image processing device that can suppress only a virtual image in a radar image. A radar image processing device (1) according to the present invention is characterized by being provided with: a refocusing unit (10) that receives input of a radar image and changes focus of the radar image; a virtual image determination unit (11) that determines, on the radar image of which the focus has been changed by the refocusing unit, pixels including a virtual image; and a virtual image suppression unit (12) that changes the value of the pixels determined, by the virtual image determination unit, to include the virtual image on the radar image, of which the focus has been changed by the refocusing unit. The radar image processing device (1) according to the present invention can be used for a synthetic aperture radar (SAR).
