Spatial sampling ambiguities in synthetic aperture sonar for broadside and squint look operations
, 1998 This paper presents results from an investigation into the position and relative magnitude (Ambiguity to Signal Ratio, ASR) of azimuth ambiguities in broadside and squint look Synthetic Aperture Sonar (SAS). The number of track positions for which signal

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)

Impact of Azimuth Ambiguities on Interferometric Performance [PDF]
IEEE Geoscience and Remote Sensing Letters, 2012 The impact of azimuth ambiguities on interferometric performance in terms of phase bias and standard deviation of the interferometric phase is analysed, resorting to the interferogram statistics for jointly circular Gaussian processes.

Accurate Reconstruction and Suppression for Azimuth Ambiguities in Spaceborne Stripmap SAR Images [PDF]
IEEE Geoscience and Remote Sensing Letters, 2017 In this letter, an accurate mathematical model for azimuth ambiguity in stripmap synthetic aperture radar (SAR) images is first constructed, with an azimuth ambiguity factor (AAF) defined as the residual amplitude and phase terms of ambiguities.

Adaptive Removal of Azimuth Ambiguities in SAR Images
IEEE Transactions on Geoscience and Remote Sensing, 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.

An Azimuth Ambiguity Suppression Method Based on Local Azimuth Ambiguity-to-Signal Ratio Estimation
IEEE Geoscience and Remote Sensing Letters, 2020Azimuth ambiguity greatly affects the image quality and application of synthetic aperture radar (SAR). Several azimuth ambiguity suppression methods have been proposed; however, these methods cannot remove the ambiguity completely and only the first-order ambiguity has been considered. Hence, in this letter, a novel method based on Wiener filtering and
