Abstract
Autofocus is critical for inverse synthetic aperture radar (ISAR) imaging. This paper develops two new approaches of autofocus for ISAR imaging based on beamforming. The ISAR observation model is established and the proposed approaches are described in detail. The relationships of the two approaches are identified and their statistical performance analysed. The results of processing simulated and real data confirm the validity of proposed approaches.
