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.

Frequently Asked Questions

  • Engineers and asset owners who work with InSAR results and want to know how much confidence to place in them.

  • How sorting InSAR measurement points into Point Scatterers (PS), Distributed Scatterers (DS) and Weak Scatterers (WS) affects how results are read, how accurately they are located and how reliable they are.

  • On large assets such as power plants. Filtering to true PS points makes it easier to link movement to specific pipes, tanks or structures.
