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

Adaptive removal of azimuth ambiguities in SAR images
IEEE Transactions on Geoscience and Remote Sensing, 2005We 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. The algorithm exploits a band-pass filter to select that portion of the azimuth spectrum that is less influenced by ...

A Novel Range-Azimuth Joint Modulation Scheme for Range Ambiguity Suppression
IEEE Transactions on Geoscience and Remote Sensing, 2022Range ambiguity is a technical challenge for current spaceborne synthetic aperture radar (SAR) systems. To this end, a novel range-azimuth joint modulation transmission scheme is proposed, and the corresponding imaging processing and performance analysis are detailed.

Suppressing azimuth ambiguity in spaceborne SAR images based on compressed sensing
Science China Information Sciences, 2012In spaceborne synthetic aperture radar, undersampling at the rate of the pulse repetition frequency causes azimuth ambiguity, which induces ghost into the images. This paper introduces compressed sensing for azimuth ambiguity suppression and presents two novel methods from the perspectives of system design and image formation, known as azimuth random ...
