Comparison of optimization procedures for radar scattering matrices

Summary form only given. Basic principles of radar polarimetry were introduced, and various optimization procedures for the propagation (scattering) range operator equation and the received power expressions were presented and compared. It was assumed that the radar is a complete coherent dual orthogonal (A,B) transmit/receive antenna system of high channel isolation and antenna sidelobe reduction, where in the case of wave interaction with a discrete stationary point target the propagation (scattering) matrix is given by the 2*2 coherent Jones (Sinclair) matrix and/or the 3*3 or 4*4 complex covariance matrix, and the 4*4 Mueller (Kennaugh) power density matrix for the symmetric or the asymmetric partially coherent cases, respectively. Separate optimization procedures were introduced for the symmetric case, demonstrating that for the coherent (deterministic) scattering scenario the solutions are identical, and so approximately also for the partially polarized case, whereas for the partially coherent case a more elaborate optimization procedure for the 3*3 covariance and/or 4*4 Mueller matrices is employed.<>
