SAR moving object imaging using sparsity imposing priors
(Springer, 2017)Synthetic aperture radar (SAR) returns from a scene with motion can be viewed as data from a stationary scene, but with phase errors due to motion. Based on this perspective, we formulate the problem of SAR imaging of ... -
SAR moving target imaging using group sparsity
(European Signal Processing Conference, EUSIPCO, 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. SAR data from a scene with motion can ... -
Seismic microzonation of Bursa/Güzelyalı in Turkey: a study on the compatibility of 1d dynamic analysis and microtremor measurements
