Abstract :
In this communication, the combined field integral equation for perfect electrically conducting scatterers is combined with the stochastic Galerkin method (SGM) to model the impact of stochastic variations of the shape of the scatterer on the radar cross-section and on the induced current distribution. The SGM is compared to the stochastic collocation method (SCM) and it is shown that for a modest number of random variables the SGM is a good alternative to the SCM.
