A method for assisting in decision-making for multilayer radar absorbent coverings
Abstract
A multicriteria optimization method for multi-layer radar absorbent coverings destined for use with existing aircraft is presented. This technique first uses an optimization procedure with nonlinear constraints, specifically the generalized projected gradient method. Next, the application of a modified multi-criteria decision theory fuses several design criteria and provides decision assistance to the designer. The method permits the use of three fusion laws, one based on the Dempster-Shafer theory of evidence, and two based on fuzzy set theory. Experimental results of the proposed method are presented. They concern materials of the same class configured with three layers, as well as materials of different classes configured with one to five layers.
