Title
Motion compensation for high-resolution automobile-SAR
Abstract
This paper concerns the compensation of track deviations in high-resolution automobile synthetic aperture radar (SAR). We establish the geometry in which the automobile SAR raw data is acquired. Based on the derived model, the research investigates the impact of track deviations on the final focused image quality and we propose motion compensation (MOCO) strategy which can be applied to obtain a well-focused SAR image. This paper presents how to obtain the accurate positions of the antenna phase center (APC) using the velocity and attitude angles measured by inertial navigation system (INS)/global positioning system (GPS), and proposes a new method to compensate the forward velocity errors which are decomposed into two components and compensated individually, that is, high-order and low order phase compensation. Finally, the results from real data are presented to validate the whole analysis and the proposed procedure.
