Coherence of synthetic aperture sonar and radar (SAS and SAR) data is a fundamental property that allows all manner of data exploitation and information extraction. Its understanding is crucial to maximizing the utility of SAR/SAS data, particularly in change-map generation for coherent change detection (CCD). This presentation will discuss the property of coherence as it relates to a variety of SAR/SAS CCD and exploitation techniques, as well as what factors influence it, and its quality in detecting obscured objects.
