MULTI-OUTPUT LEAST SQUARE SUPPORT VECTOR MACHINE FOR THE RECONSTRUCTION OF PERFECT ELECTRIC CONDUCTOR BELOW ROUGH SURFACE

To save the computation time and improve the accuracy of reconstruction results by support vector machine (SVM), a multi-output least square SVM (LS-SVM) algorithm is proposed to reconstruct the position of a 2-D perfect electric conductor (PEC) cylinder below a rough surface. Firstly, the scattered electromagnetic field at a number of observation positions is calculated by the method of moment to generate the training and testing data. Then the multi-output LS-SVM is trained to reconstruct the coordinate of the object center. Numerical results show that this approach is accurate and efficient even with some additive Gaussian noise.
