In 1987.Kostinski established a mathematical model for obtaining optimum antenna polarizationfor target discrimination in clutter[2],but be did not take into consideration the optimal polarization ofthe receiving antenna. Starting from the authors papers published in 1990[5,61,the author now proposesa new mathematical model that overcomes the shortcoming of Kostinski's model.Employing this model,the author presents two methods of solution.One method is the conversion of the problem into binary algebraic equations.The conversion is accomplished by making use of singular value decomposition and the method of optimization. The secondmethod is the conversion of the problem into a bilinear form. The conversion is accomplished by utilizingMuellcr matrix and Stokes vectors. The bilinear problem is then solved by a cross itCrative method.TheresultS complutcd by the two methods are in full agreement.
