In this paper, the Bistatic scattering coefficient from one - dimension Gaussian perfect conductor random rough surface is computed by the Moment method in Dirichlet boundary condition, and the basis function is taken as the pulse function and weighting function in the point matching method.

Moment Method conductor will surface current, mixed-use electromagnetic field integral equation Moment Method.

The electromagnetic scattering problem is often treated with integral equation and moment of method, and the calculation of matrix element is one of the most important factors that affecting the accuracy and efficiency of method of moment.

Firstly, the basic principles of MOM are reviewed, including the selection of integral equations, the choice of basis function and weight function, the solution of matrix equation and so on.

Based on the moment matrix and voltage feed, a new definition of eigen-driven model in moment method is proposed, or one element of the array fed with others short.

First of all, the basis of the MRTD method is studied. In Chapter 2, wavelets analysis and multiresolution analysis, the mathematical basis, are introduced, and the characteristics of the wavelets basis functions, including orthonormality, compact support, multiresolution and so on, are also introduced. The advantages of the applications of these functions to the numerical electromagnetic calculations are discussed. In Chapter 3, the algorithm basis of MRTD: the combination of the wavelets and the method of moments is studied. This Chapter shows that the MoM based MRTD method is the combination of wavelets and MoM using Galerkin sampling.

As the conventional method of moment has some disadvantages in geometrical modeling and computational work, the high order MoM and bilinear surface technology are used in studying the scattering electromagnetic characteristics of dielectrically coated conducting targets.

The theory of the method of moments is introduced firstly in this thesis, and some basic functions and testing functions are discussed, how to compute the radar cross sections of two-dimensional conducting objects and dielectric scatterers are also elaborated.

Based on a certain typical kind of communication and command armored car, a method of complicated face meshing by the MOM is proposed and the text file with Visual LISP language embedded in AutoCAD is dealt with.
