Scattering from Coated Missile

This application note shows comparison between monostatic scattering from metallic and coated missiles. Three missile models are created and simulated by using WIPL-D Pro CAD. WIPL-D Pro CAD software is suited for easy and fast creation of complex 3D geometry models. It allows importing models from various CAD formats. It also allows creating models from the scratch using built-in primitives.

The dielectric layers were added using WIPL-D Pro. They are added by using Copy\Layer manipulation applied after meshing the CAD model. It enables modelling of arbitrary thin layer where both surfaces of the layer are meshed in the same way. The same meshing of the close surfaces is very important due to accuracy of geometry modelling and due to simulation accuracy.

Three simulated models are metallic model, coating the missile with a dielectric layer and adding one more dielectric layer. The simulations were carried out on standard desktop PC empowered with low-end Nvidia GPU card. CPU is used for matrix fill, while GPU is used for matrix inversion. Monostatic analysis with many excitations is performed very fast, additional time compared to bistatic RCS simulations is rather small.
