Tracking and refocussing of moving targets in multichannel SAR data


Henke, Daniel; Meier, Erich (2015). Tracking and refocussing of moving targets in multichannel SAR data. In: Geoscience and Remote Sensing Symposium (IGARSS), 2015 IEEE International, Milan, Italy, 26 July 2015 - 31 July 2015, 3735-3738.

Abstract

Moving targets in Synthetic Aperture Radar (SAR) data impose several challenges for SAR processing. In full-aperture SAR images, moving objects appear smeared and/or displaced. In previous studies, we showed that a combination of sub-aperture processing, feature extraction, unscented Kalman filtering and multi-target hypotheses can reliably detect and track moving objects. In this paper, we present some extensions to the tracking algorithm itself, show results on a newly acquired data set and demonstrate how the estimated trajectories of the moving objects can be utilized to refocus the originally smeared objects.
