Compressed Isar Autofocusing: Experimental Results

This paper is reporting some experimental results of compressed inverse synthetic aperture radar (ISAR) imaging. The autofocusing procedure accepting sparse echoes is developed, which consists of range alignment and phase correction as in conventional ISAR processing. Range alignment is implemented through minimizing the entropy of the average range profile, while phase correction is accomplished using the eigenvector method. The presented results have suggested further applicability of compressed sensing (CS) in the ISAR technique.
