Abstract
The radar deviceincludes radar signal transmission and receiving meansfor obtaining radar signals, based on reflected waves received by a plurality of receiving antennas, movement estimation meansfor estimating a movement of an object that may appear in a radar image, movement discretization meansfor discretizing the estimated movement, signal dividing meansfor dividing the radar signals into a plurality of groups, Fourier transform processing meansfor applying Fourier transform to the radar signals of each of the groups, phase-compensation and synthesis processing meansfor synthesizing results of the Fourier transform after performing phase compensation corresponding to the movement of the object on the results of the Fourier transform, and imaging processing meansfor generating the radar image from the synthesized result of the Fourier transform.
