Abstract

An apparatus and method for detecting the polarization signature of radar signals reflected from a target immersed in clutter. The signal to be transmitted is split into individual horizontal, vertical, and 45° polarized signals that are individually frequency shifted, and transmitted simultaneously. The reflected signals are processed in individual horizontal, vertical and 45° channels so as to derive Stokes vectors corresponding to each polarization and describing the scattered field associated with that polarization. The signals representing the Stokes vectors are applied to a matrix computer which provides signals representative of a Mueller matrix which describes how the transmitted signal was transformed by the target and thus constitutes the polarization signature of that target.
