Comparison of non-coherent change detection methods in SAR imagery

Change detection is the process of identifying differences that have occurred in the terrain surface (EO) at different times (e.g. short time or long time changes, depending on the application). Change detection techniques vary depending on the data source - optical or radar (SAR) imagery. Since both sensors work with different geometry and frequency bands, different distortions and noises are present. Hence different kinds of change detection methods need to be introduced. In this article author will focus on SAR imagery non-coherent change detection.
