Moving Target Tracking in Single- and Multichannel SAR

Methods for moving target tracking in single- and multichannel synthetic aperture radar (SAR) are presented and evaluated using data from the F-SAR system. An approach based on temporal and spatial overlapping SAR images, image statistics, and multitarget unscented Kalman filtering showed promising...

Description
Summary:Methods for moving target tracking in single- and multichannel synthetic aperture radar (SAR) are presented and evaluated using data from the F-SAR system. An approach based on temporal and spatial overlapping SAR images, image statistics, and multitarget unscented Kalman filtering showed promising results for a single-channel linear SAR experiment. Here, we extend this approach to integrate along-track multichannel data, combine single- and multichannel extraction methods, and verify our results on nonlinear test data on all the different extraction methods. The results are validated and compared with ground-based measurements on a highway section, demonstrating the accuracy of the presented method.
