Investigations on the Advanced SAR Processing Algorithms for Security Applications With Distributed Sensing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
A distributed airborne/spaceborne synthetic aperture radar (SAR) system that consists of a set of monostatic and/or bistatic SARs offers many advantages thanks to the bi-/multiaperture reception.

Moving Target Signals in High Resolution Wide Swath SAR [PDF]

, 2008
In this paper the impact of two high resolution wide swath synthetic aperture radar imaging techniques, extraction of signals from azimuth subsampled spectra and subpulse azimuth beamsteering on transmit, on ground moving target signals is analyzed ...

The Geometry of Spaceborne Synthetic Aperture Radar

, 2018
The paper defines a new coordinate system that was developed in 1977-78 for the world's first digital synthetic aperture radar (SAR) ground processor for images from the Seasat-A satellite. The coordinate system is for the range-Doppler paradigm in the context of a spaceborne platform orbiting a rotating planet.
