Efficient Autofocus Chain for ISAR Imaging of Non-Uniformly Rotating Target

Conventional approaches to inverse synthetic aperture radar (ISAR) imaging of a non-uniformly rotating target are not optimal in terms of reconstructed image quality and/or computation time. Motivated by the problems of conventional approaches, we introduce an efficient autofocus chain for ISAR imaging of a non-uniformly rotating target. The most distinct feature of the proposed autofocus chain is...
