Polarimetric recovery of high frequency scattering centers from bistatic-monostatic scattering matrix data

The object of this investigation is to develop a multistatic inverse scattering algorithm using the complete polarimetric scattering data. At high frequencies the electromagnetic scattering from a complex object is modeled by certain scattering centers. This paper develops, in detail, the high frequency (physical optics) bistatic and monostatic scattering matrix properties of a flat plate model of such a scattering center. Analyzing these model scattering matrices, a procedure for recovering the high frequency scattering centers from the multistatic polarimetric data is reported. It is suggested that the knowledge of the locations and the local geometries of these scattering centers can be useful in developing identification and pattern recognition algorithms.
