Azimuth ambiguity suppression for spaceborne SAR based on PRF micro-variation
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013Spaceborne synthetic aperture radar (SAR) has been proved highly significant for remote sensing of the Earth. The image quality is constrained by the system design and the image processing technology, azimuth ambiguity is one of the most important factors.

Doppler Ambiguity Resolving in Compressed Azimuth Time and Range Frequency Domain
IEEE Transactions on Geoscience and Remote Sensing, 2008For high-quality synthetic aperture radar (SAR) processing, Doppler centroid ambiguity resolving is an essential procedure. A novel method for the resolution of Doppler ambiguity is presented which exploits the fact that, in the compressed azimuth time and range frequency domain, all targets span the same range frequency bandwidth and exhibit the same ...

Azimuth Ambiguity Mitigation in SAR
Azimuth ambiguities occur during the acquisition of SAR data as alias effects and overlap with the useful signal, thus degrading its quality. In the case of data recorded with the F-SAR system of DLR, strong, point-like scatterers cause the worst azimuth

Removing The Azimuth Ambiguities Of Point Targets In Synthetic Aperture Radar Images
[Proceedings] IGARSS '92 International Geoscience and Remote Sensing Symposium, 2005This paper proposes a method for removing the azimuth ambiguities of point targets in SAR images. The basic idea is to generate a two dimensional reference function for the SAR processing which provides, in addition to the matched filtering for the unaliased part of the received signal, the deconvolution of the azimuth ambiguities of point targets.
