Polarization Utilization in Radar Target Reconstruction
Abstract
Basic theories for polarization utilization in radar target reconstruction are presented and a general literature review with many pertinent references is given. The mathematical descriptions of polarization in terms of the Poincare polarization sphere are introduced and the relationships existing among the radar scattering matrix (S), the Stokes reflection matrix (M), the modified Mueller matrix (Mm), and the coordinates of the related co-polarization and cross-polarization nulls on the Poincare sphere are derived. It is shown that a scattering phenomenon can be uniquely expressed given the elements of either one of (S), (M), (Mm) or the coordinates of the optimal polarizations, i. e. unique inversion relations among the four equivalent representations exist which is relevant to target polarization synthesis. The developed theories are verified by computer computation using measurement data and/or model scattering data as inputs. The computer programs are listed and examples of our optimal polarization analysis are presented for the monostatic, relative phase case. Single perfectly conducting target shapes and some sea clutter testing models with and without target were chosen; and our studies demonstrate clearly that the optimal polarization concept introduced by KENNAUGH is very useful in radar target analysis as will be further pursued in other forthcoming reports.
