SYNTHETIC-APERTURE-RADAR APPARATUS AND METHOD FOR PRODUCTION OF SYNTHETIC- APERTURE-RADAR IMAGES OF MOVING OBJECTS

摘要

A SAR device includes a radar transceiver which emits an electromagnetic pulse and provides a radar signal in response to an echo of the electromagnetic pulse; And a processing device configured to generate a SAR image of the moving object from the radar signal. The processing apparatus includes a first processing module for applying the translational motion compensation to the center reference point of the moving object at the sub-opening of the radar signal; A second processing module for performing phase compensation with reference to a single center reference point; And a third processing module for applying phase compensation to the radar signal as a function of the estimated phase component and normalization parameter of the ball point to distance in the range between the center reference point CRP and the ball point CP.
