Rotorcraft-Borne 3-D Forward-Looking Mimo Sar Autofocusing
RADAR SENSOR TECHNOLOGY XXV(2021)
Abstract
This paper considers the autofocusing problem for a rotorcraft-borne forward-looking multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) system. Autofocusing is critically important for forward-looking MIMO SAR imaging, since the radar position errors due to the limited precision of navigation systems can severely degrade the imaging quality. In this paper, we propose a novel autofocusing method to address the radar position errors, resulting from both translational and rotational motion errors, for forward-looking MIMO SAR imaging. The effectiveness and efficiency of the proposed autofocusing algorithm are demonstrated by using several numerical experiments.
