Sequential estimator for distributed scatterer interferometry [PDF]
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016 The launch of the wide-swath SAR missions with short repeat-pass cycles, such as Sentinel-1, will soon provide an unprecedented large InSAR data archive. Time-series analysis on the rapidly growing data will thus become computationally demanding for a systematic monitoring of earth surface deformation.

Parametric scatterer extraction method for space‐target inverse synthetic aperture radar image CLEAN
IET Radar, Sonar & Navigation, 2023 Owing to the time variance of the inverse synthetic aperture radar (ISAR) imaging plane of space targets, scatterers with large heights relative to the imaging plane migrate through several Doppler cells. This defocussing in the azimuth direction of each
