SAR moving target imaging using group sparsity [PDF]

open access: yes, 2013
SAR imaging of scenes containing moving targets results in defocusing in the reconstructed images if the SAR observation model used in imaging does not take the motion into account.

Segmentation Of SAR Images

open access: yesInternational 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.
