On the Impact of Scatterer Classification on the InSAR-derived Insights
Technical Paper
This paper addresses the ambiguity in classifying InSAR scatterers (Point Scatterers, PS, vs. Distributed Scatterers, DS) and the impact of this classification on the interpretation of results.
Learn how an extended scatterer classification procedure identifies "True PS" for superior geopositioning while leveraging "Weak Scatterers" for necessary spatial coverage and improved statistical reliability.
Discover why filtering InSAR data to Point Scatterers (PS) only is crucial for clear interpretation of movement on large assets like power plants, isolating motion to specific infrastructure (pipes, tanks).
Understand how including Weak Scatterers (WS) for small assets significantly increases sample size, lowering the standard deviation of displacement rates and increasing the reliability of derived statistics.
