Accounting for Azimuth Ambiguities in Interferometric Performance Analysis [PDF]
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012 Azimuth ambiguities affect the interferometric performance of SAR systems, causing a bias in the interferometric phase and a modulation of the interferometric coherence, as also visible in some TanDEM-X interferograms.

Ambiguity Suppression by Azimuth Phase Coding in Multichannel SAR Systems [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2011 The Azimuth Phase Coding (APC) technique, proposed to suppress range ambiguities in conventional SAR systems, stands out for its low implementation complexity and its effectiveness for point and distributed ambiguities.

Azimuth Phase Coding for Range Ambiguity Suppression in SAR [PDF]
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004 A novel ambiguity suppression technique is proposed. Range ambiguities in synthetic aperture radar (SAR) images are eliminated with an azimuth filter after having applied an azimuth phase modulation to the transmitted pulses and a corresponding ...

Suppressing the Azimuth Ambiguities in Synthetic Aperture Radar Images.
IEEE Transactions on Geoscience and Remote Sensing, 1993 This paper proposes a method for removing the azimuth ambiguities from synthetic aperture radar (SAR) images. The basic idea is to generaste a two-dimensional reference function for SAR processing which provides, in addition to the matched filtering for

On the characteristics of ASCAT wind direction ambiguities [PDF]
Atmospheric Measurement Techniques, 2013 The inversion of the Advanced Scatterometer (ASCAT) backscatter measurement triplets generally leads to two wind ambiguities with similar wind speed values and opposite wind directions.

Calibration of SIMO Formations with Azimuth Ambiguities
IEEE Transactions on Geoscience and Remote SensingFormations of small satellites are gaining momentum as an alternative to single synthetic aperture radar (SAR) systems, allowing them to improve performance and reduce costs. Each sensor operates with a low pulse repetition frequency (PRF), so swath size

Azimuth Ambiguity Suppression in SAR Images Based on Compressive Sensing Recovery Algorithm
Leida xuebao, 2016 Azimuth ambiguities appear widely throughout spaceborne Synthetic Aperture Radar (SAR) images. If the ambiguous energy is relatively strong, a large number of brilliant areas or points will emerge, which may be erroneously judged as actual targets.

SAR Image Processing with Suppression of the Azimuth Ambiguities.
, 1992 This paper proposes a method for removing the azimuth ambiguities of point targets in SAR images. The proposed method for suppressing the azimuth ambiguities of point targets has a substantial significance in enabling the PRF constraints in the SAR ...
