Azimuth Ambiguity Suppression for Multichannel Geosynchronous Spaceborne-Airborne Bistatic SAR
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Due to the high altitude illuminator and the separation of the receivers and transmitter, Geosynchronous (GEO) spaceborne-airborne bistatic SAR (GEO BiSAR) is more flexible and accessible in remote sensing applications. However, by introducing a high speed airborne platform as receiver, azimuth spectrum aliasing occurs. In order to suppress the azimuth

Azimuth ambiguity suppression based on minimum mean square error estimation
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015An innovative algorithm to suppress the strong azimuth ambiguity in single-look complex (SLC) synthetic aperture radar (SAR) images is presented. The basic idea is to construct a subspace with low ambiguous power and project the original image to the aforementioned subspace to suppress the azimuth ambiguity by the minimum mean square error estimation ...

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 ...

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.
