DSENet: A Detail and Semantic Enhanced Network for Video SAR Moving Target Shadow Detection

Remote Sensing
In video synthetic aperture radar (Video SAR), target motion causes defocusing, making it impossible to determine the target’s real-time position using reflected echoes.

A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]

, 2010
Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of
