Abstract
This paper discusses the use of high altitude airborne interferometric synthetic aperture radar (IFSAR) operations for concurrent severe storm damage data collection. The primary storm damage observable is changes in surface topography induced by storm effects. The surface topography in the form of a digital surface matrix (DSM) derived from concurrent IFSAR operations is compared to an archived DSM collected prior to the storm. Information on storm damage is developed from analysis of DSM changes. Combined with a-priori photo and radar imagery, the technique provides means for detection, location, quantification and characterization of storm damage. The paper discusses limitations to the concept due primarily to radar signal propagation effects. Results of simulations of IFSAR measured surface topography are presented.
