A SAR (Synthetic Aperture Radar) system usually collects huge amount of data, and focusing of the raw data acquires complex range varying phase compensation techniques, which are generally performed off-board. The large amounts of data generated have to be stored on-board or be transmitted to a ground station via a dedicated data link. Therefore, some form of compression on the raw data provides an...
Synthetic aperture radar (SAR) is an imaging technique, which provides high-resolution images. The high resolution in the range direction is achieved by using large bandwidth signals and that in the azimuth direction is achieved by synthesizing a large aperture antenna using platform motion. The unique data collection geometry of SAR system requires that huge amounts of raw data be processed before...
Multiresolution synthetic aperture radar (SAR) image formation has been proven to be beneficial in a variety of applications such as improved imaging and target detection as well as speckle reduction. SAR signal processing traditionally carried out in the Fourier domain has inherent limitations in the context of image formation at hierarchical scales. We present a generalized approach to the formation...
