Title:
RADAR DEVICE, IMAGING METHOD, AND IMAGING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/261525
Kind Code:
A1
Abstract:
This radar device 10 comprises a radar signal transmission and reception means 11 for acquiring radar signals on the basis of reflected waves received by a plurality of reception antennas, a movement estimation means 12 for estimating the movement of an object that may appear in a radar image, a movement discretization means 13 for discretizing the estimated movement, a signal division means 14 for dividing the radar signals into a plurality of groups, a Fourier transform processing means 15 for subjecting each of the groups of radar signals to a Fourier transform, a phase-compensation/combination processing means 16 for subjecting the Fourier transform results to phase compensation corresponding to the movement of the object and then combining the Fourier transform results, and an imaging processing means 17 for generating a radar image from the combined Fourier transform results.
