Koherensprodukt fra Sentinel-1

open access: yes, 2022
Koherens er en parameter beregna fra målinger av syntetisk aperturradar (SAR), som kan ha stor nytteverdi i analyse av SAR-bilder. Den brukes her til klassifisering og kartlegging av landområder, måldeteksjon og endringsdeteksjon for ulike landanvendelser, samt i estimering av biofysiske og geofysiske størrelser.
