NARROWBAND INTERFEROMETRY AND THE POLARIZATION SCATTERING MATRIX

Abstract

Two previous papers have described the concept and some of the applications of Narrowband Interferometry, using monostatic and multistatic radars (at small bistatic angles) to obtain two and three dimensional 'images' of targets in terms of their scattering centers. The method involves taking finite Fourier transforms of measured narrowband amplitude and phase data to resolve individual scattering centers in 'Doppler' at each radar site. The present paper extends these methods in two directions. The class of scattering centers considered is widened to include not only isotropic point scatterers as before but also point dipoles, as representatives of orientable scattering centers. The theory is broadened to involve the Polarization Scattering Matrix, so that the polarization behavior of the individual resolved scatterers can be determined as aids to their recognition.
