Abstract :
Synthetic Aperture Radar Coherent Change Detection (SAR CCD) is a sensitive change detector capable of finding ground surface height changes on the order of a radar wavelength. SAR CCD also has a high false alarm rate, with many false alarms caused by vegetation that is easily displaced by wind, rain, etc. This work introduces a robust method for detecting long curving structures in this challenging medium. To demonstrate the accuracy of the method, we test it on the task of automatically distinguishing curving tire tracks from background clutter.
