N2 - A mixed mesh algorithm is developed for the integral equation modeling of scattering by three dimensional complex radar targets that consist of conducting surfaces and radar absorbing materials. The integral equation combines the surface integral equation (for conducting surfaces) and the volume integral equation (for dielectric material regions). The mixed mesh element scheme is proposed to model the complex scatterers. In this scheme, the surface is modeled by a set of triangles and quadrangles, and the dielectric volume is modeled by a set of tetrahedrons, prisms of triangle base, and prisms of quadrangle base (the hexahedron). The simulation shows that as long as the average edge length remains the same, the results from single element mesh and combined element mesh are of the same order, but the later uses less number of unknowns, less computing resources, and sometimes less iteration numbers.
