Abstract

Autofocusing is an important step for inverse synthetic aperture radar (ISAR) imaging, while traditional autofocusing algorithms often fail in sparse aperture (SA) case. The residual phase error due to the imperfect motion compensation cannot be ignored for the compressive sensing (CS) based SA ISAR imaging. To tackle this issue, an autofocus-coupled approximate message passing with unitary transformation (AFUTAMP) algorithm for SA ISAR imaging is proposed in this paper. The phase error estimation process is introduced to the UTAMP framework for autofocusing, which enable UTAMP to simultaneously complete ISAR image reconstruction and autofocus, thereby leading to excellent performance of imaging and autofocusing. The effectiveness and superiority of the proposed algorithm are verified by the simulation results and experimental results based on measured data.
