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

Calibration Issue in SMART Synthetic Aperture Radar Based on Scan-On-Receive [PDF]

, 2009
A new spaceborne Synthetic Aperture Radar (SAR) system based on SCan-On-REceive (SCORE) algorithm has been recently proposed in order to overcome the trade-off between spatial resolution and swath wide of current SAR systems. The compound architecture of

Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]

, 2010
Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

A Fast Back Projection Algorithm for Spotlight Mode Bi-SAR Imaging

Leida xuebao, 2013
A Fast Back Projection (FBP) algorithm for spotlight mode Bistatic Synthetic Aperture Radar (Bi-SAR) was presented. Sync channel signal from land receiver was taken as matched filter for echo signal in the phase of range compression, and the secondary ...
