Spaceborne SAR Imaging Algorithm for Coherence Optimized. [PDF]
PLoS ONE, 2016 This paper proposes SAR imaging algorithm with largest coherence based on the existing SAR imaging algorithm. The basic idea of SAR imaging algorithm in imaging processing is that output signal can have maximum signal-to-noise ratio (SNR) by using the ...

Concept, System, and Method of Holographic Synthetic Aperture Radar
Leida xuebao, 2020 Over time, Synthetic Aperture Radar (SAR) imaging techniques have been developed from twodimensional SAR, two-and-a-half-dimensional SAR (InSAR), and three-dimensional SAR to multi-dimensional SAR. This has led to great technological achievements.

SAR Image Segmentation with GMMs [PDF]
International Conference on Radar Systems (Radar 2017), 2017 This paper proposes a new approach for Synthetic Aperture Radar (SAR) image segmentation. Segmenting SAR images can be challenging because of the blurry edges and the high speckle. The segmentation proposed is based on a machine learning technique.

International Geoscience and Remote Sensing Symposium, 'Remote Sensing: Moving Toward the 21st Century'., 1989 Based on an SAR speckle statistical model, the authors investigate the feasibility of segmenting SAR images based on a gray-level histogram for one-look and multilook processed SAR images. The classification errors are evaluated and a procedure for the multilevel thresholding of SAR images is devised.

Progressive SAR imaging technique [PDF]
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010 A progressive SAR imaging technique is proposed as a novel SAR raw data processing scheme in this paper. Different from the classic SAR imaging algorithms which focus the SAR raw data as a whole regardless of the backscattering signal, the novel scheme discriminate the backscattering signal and choose the proper ones to be focused progressively ...
