Target decomposition analysis of SIR-C imagery for characterization of scattering mechanisms and their dependence on observation parameters

Multitemporal Shuttle Imaging Radar C (SIR-C) images taken over the Sarobetsu test site were analyzed using target decomposition to characterize the scattering mechanisms and relate them with the target conditions. Analysis results indicate a change in the dominant scattering mechanism with a change in the observation parameters, which is reasonably related with the surface conditions estimated from aerial photographs.
