Advanced Digital Beamforming Concepts for High Performance Synthetic Aperture Radar (SAR) Imaging [PDF]

, 2009
This paper reviews advanced multi-channel SAR system concepts for the imaging of wide swaths with high resolution. Several novel system architectures employing both direct radiating arrays and reflector antennas fed by a digitial array are introduced ...

Synthetic aperture sonar imaging using compressive sensing and an ultrasound transducer array [PDF]

, 2013
Includes bibliographical references.Compressive sensing (CS) also known as compressive sampling is a technique used to reconstruct or recover the full-length of a signal with only a few non-adaptive measurements.

Bi- and Multistatic SAR: Potentials and Challenges [PDF]

, 2004
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas which are mounted on separate platforms. Such a spatial separation has several operational advantages which will increase the capability, reliability ...

Ultra Wide Swath Imaging With Multi-Channel SAR Systems [PDF]

, 2008
Multi-channel radar systems allow for overcoming the inherent limitation of conventional synthetic aperture radar (SAR). An example is the combination of digital beamforming on receive in elevation with multi-aperture SAR signal reconstruction in azimuth

The Staggered SAR concept: Imaging a wide continuous swath with high resolution [PDF]

, 2013
Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...

Experimental Performance Analysis of Digital Beam Forming on Synthetic Aperture Radar [PDF]

, 2008
In this paper, we present the experimental results of a DBF performance to achieve High-Resolution Wide-Swath (HRWS) SAR concept. The measurements were accomplished by a ground-based DBF SAR system exploiting a switched antenna array on the receiver. SAR
