A Robust Minimum-Entropy-Based Time-Domain Algorithm for Azimuth Multichannel HRWS SAR Imaging
IEEE AccessAzimuth multichannel (AMC) synthetic aperture radar (SAR) system, utilizing digital beam forming (DBF) processing, is capable of achieving high-resolution and wide-swath (HRWS) focusing, presenting significant potential for Earth observation ...

, 2019 In synthetic aperture radar (SAR) images, azimuth ambiguity is one of the important factors that affect image quality. Generally, the azimuth ambiguity-to-signal ratio (AASR) is a measure of the azimuth ambiguity of SAR images.

Young’s modulus variation with azimuth for fracture-orientation estimation
, 2018 This study focuses on developing a pragmatic and robust method in the estimation of fracture orientation assuming a single set of aligned fractures. The Young’s modulus in the direction of fracture orientation is larger than that in the perpendicular ...

Adaptive removal of azimuth ambiguities in SAR images
, 2005 We introduce an innovative algorithm that is capable of suppression of strong azimuth ambiguities in single-look complex (SLC) synthetic aperture radar images, to be used both for detected products and for interferometric surveys.

Analysis on TerraSAR-X Spotlight Scene Size and Sliding Spotlight Azimuth Ambiguity Ratio
, 2011 The Technical Note presents an investigation about the scene size of TerraSAR-X Spotlight mode. The TSX spotlight mode was designed in order to ensure a fixed scene size for all incidence angles, i.e. 10kmx10km for Spotlight and 10kmx5km (range x azimuth)

First demonstration of Azimuth Phase Coding Technique by TerraSAR-X [PDF]
, 2014 The disturbance generated by ambiguous echoes is at the origin of a basic limitation of Synthetic Aperture Radar (SAR) spaceborne imaging: the trade-off between spatial resolution and swath extension.
