Abstract
The measuring point information providing device of the present invention inputs an SAR image set holding at least information indicative of a reflection intensity and a phase so as to be associated with each pixel corresponding to a resolution cell within a field of vision for image capturing including a specific region. The information is generated from observation data formed of four basic polarization pairs, i.e. HH, HV, VH and VV polarization pairs observed at generally the same time. The measuring point information providing device determines a polarization pair whose reflection intensity is not less than a predetermined value or the highest with respect to each target pixel by using the input SAR image set, and generates measuring point information including at least information indicative of the determined polarization pair of the target pixel based on a polarization pair determined by the polarization pair determination unit.
