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 demodulation to the received pulses. The technique excels by actually eliminating the ambiguities rather than

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. Next, a novel framework for reconstructing and suppressing azimuth ambiguity is proposed based on the ...

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

A Novel Azimuth Ambiguity Suppression Method for Spaceborne Dual-Channel SAR-GMTI
IEEE Geoscience and Remote Sensing Letters, 2021Azimuth ambiguity degrades the quality of synthetic aperture radar (SAR) images and leads to the increase of false alarm rate in ground moving target indication (GMTI). Due to the existing azimuth ambiguity, suppression methods do not remove the first-order ambiguity completely and ignore the ambiguity above first order as well, moving target detection
