Inverse synthetic aperture radar imaging of targets with complex motion based on the local polynomial ambiguity function

, 2016
. In inverse synthetic aperture radar (ISAR) imaging of targets with complex motion, the azimuth echoes have to be modeled as multicomponent cubic phase signals (CPSs) after motion compensation.

Sparsity-driven sparse-aperture ultrasound imaging [PDF]

, 2006
We propose an image formation algorithm for ultrasound imaging based on sparsity-driven regularization functionals. We consider data collected by synthetic transducer arrays, with the primary motivating application being nondestructive evaluation.

Theory and measure of certain image norms in SAR [PDF]

, 1984
The principal properties of synthetic aperture radar SAR imagery of point and distributed objects are summarized. Against this background, the response of a SAR (Synthetic Aperture Radar) to the moving surface of the sea is considered.
