Autofocus is a key step of inverse synthetic aperture radar (ISAR) imaging. In this paper four new approaches to autofocussing based on the application of beamforming and subspace concepts to ISAR imaging are developed. Their relations to maximum likelihood (ML) estimation are identified. A common feature of these techniques is the estimation of the complex vector formed by the exponential function...
Many array signal processing algorithms have been developed to reject interfering signals and, therefore, increase the quality of the communication link. Some of them are reference-based and some others are blind, i.e., without any side information. A specific type of deterministic blind beamforming algorithms, named self-reference, is treated in the paper. Self-reference beamforming is suitable for...
