A Fast Eigenvector-Based Autofocus Method for Sparse Aperture ISAR Sensors Imaging of Moving Target

Motion compensation is of significant importance in generating high-focused inverse synthetic aperture radar (ISAR) images. The range misalignment and the phase error of each received echo are two important parameters in ISAR imaging and they need to be precisely estimated and compensated. Faced wit...
