A otimização do aprimoramento de contraste polarimétrico (OPCE) é um método amplamente utilizado para maximizar a relação de potência recebida de um alvo desejado versus um alvo indesejado (desordem). Nesta carta é proposto um novo modelo de OPCE baseado no critério de Fisher. Ao introduzir o conhecido problema de duas classes de análise discriminante linear (LDA), o modelo proposto é ampliar a distância normalizada do valor médio entre o alvo e a desordem. Além disso, é proposto um método numérico iterativo cruzado para resolver a otimização com restrição quadrática. Resultados experimentais com dados SAR polarimétricos (POLSAR) demonstram a eficácia do método proposto.

Abstract: The optimization of polarimetric contrast enhancement (OPCE) is a widely used method for maximizing the received power ratio of a desired target versus an undesired target (clutter). In this letter, a new model of the OPCE is proposed based on the Fisher criterion. By introducing the well known two-class problem of linear discriminant analysis (LDA), the proposed model is to enlarge the normalized distance of mean value between the target and the clutter. In addition, a cross-iterative numerical method is proposed for solving the optimization with a quadratic constraint. Experimental results with the polarimetric SAR (POLSAR) data demonstrate the effectiveness of the proposed method.
