Abstract
A radar signal processing device includes: a forming unit to form beams by using reception signals; a compensation unit to compensate for a phase within a range frequency; a generation unit to generate an image of each beam by applying Fourier transform in an azimuth direction to the beams (with phases compensated; an identification unit to identify a position of a target object based on the image; a calculation unit to calculate power of each beam represented by the image of each beam at a position of the target object; a computing unit to compute an antenna gain of each beam at a position of the target object; and an angle measurement unit to measure angle on the target object by performing maximum likelihood estimation of comparing the power of each beam with the antenna gain of each beam at the position of the target object.
