Clean: A false alarm reduction method for SAR CCD

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. While this detector is capable of finding small changes such as tire tracks left on the ground, it is fraught with false alarms. This paper introduces a new algorithm, the Clutter Location, Estimation, And Negation (CLEAN) method, to remove multiple classes of false alarms, enhancing the detection of true change in CCD.
