Artifact detection program and artifact detection method and artifact detection apparatus

摘要

PPROBLEM TO BE SOLVED: To highly accurately detect only artifacts by multi-polarization observation. PSOLUTION: In an artifact detection device 100 where the results of four-polarization observations using a synthetic aperture radar are previously stored as polarization characteristic data 201, a scattered component extraction unit 101 extracts a surface-scattered component, a twice-scattered component, a volume scattered component, and a helix scattered component from the polarization characteristic data 201, for each observation position. An artifact detector 104 detects, as an artifact, a region which contains a first region being an assembly of observation positions having data from which one or more kinds of scattered components have been extracted out of twice-scattered components, volume scattered components, and helix scattered components by the extraction unit 101, and a second region being an assembly of observation positions which are around the first region and have data from which surface-scattered components in a prescribed amount or more have been extracted by the extraction unit 101.
