Since the problem is considered to be 2D, the integral equations (IEs) are scalar and only the TE (transverse electric) and TM (transverse magnetic) polarizations are addressed (no cross-polarizations occur). In Chapter 1, the MoM is applied to convert the IEs into a linear system, while Chapter 2 compares the MoM with the exact solution of the field scattered by a cylinder in free space, and with the Physical Optics (PO) approximation for the scattering from a plate in free space. Chapter 3 presents numerical results, obtained from the MoM, of the coherent and incoherent intensities scattered by a random rough surface and an object below a random rough surface. The final chapter presents the same results as in Chapter 3, but for an object above a random rough surface. In these last two chapters, the coupling between the two scatterers is also studied in detail by inverting the impedance matrix by blocks.\u003c\/p\u003e\u003c\/font\u003e\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cfont size=\"3\"\u003e\u003cp\u003ePreface ix\u003c\/p\u003e \u003cp\u003eIntroduction xi\u003c\/p\u003e \u003cp\u003e\u003cb\u003eChapter 1 Integral Equations for a Single Scatterer: Method of Moments and Rough Surfaces 1\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e1.1 Introduction 1\u003c\/p\u003e \u003cp\u003e1.2 Integral equations 2\u003c\/p\u003e \u003cp\u003e1.2.1 TE and TM polarizations and boundary conditions 2\u003c\/p\u003e \u003cp\u003e1.2.2 Electric and magnetic currents for a 2D problem 3\u003c\/p\u003e \u003cp\u003e1.2.3 Huygens’ principle and extinction theorem 4\u003c\/p\u003e \u003cp\u003e1.2.4 Radar cross-section (RCS) 8\u003c\/p\u003e \u003cp\u003e1.2.5 Normalized radar cross-section (NRCS) 10\u003c\/p\u003e \u003cp\u003e1.3 Method of moments with point-matching method 12\u003c\/p\u003e \u003cp\u003e1.4 Application to a surface 14\u003c\/p\u003e \u003cp\u003e1.4.1 The Dirichlet boundary conditions 14\u003c\/p\u003e \u003cp\u003e1.4.2 The Neumann boundary conditions 16\u003c\/p\u003e \u003cp\u003e1.4.3 General case 17\u003c\/p\u003e \u003cp\u003e1.4.4 Impedance boundary condition 18\u003c\/p\u003e \u003cp\u003e1.5 Forward–Backward (FB) method 19\u003c\/p\u003e \u003cp\u003e1.6 Random rough surface generation 21\u003c\/p\u003e \u003cp\u003e1.6.1 Statistical parameters 21\u003c\/p\u003e \u003cp\u003e1.6.2 Generation of a random profile 23\u003c\/p\u003e \u003cp\u003e1.6.3 Simulations 26\u003c\/p\u003e \u003cp\u003e1.6.4 Conclusion 30\u003c\/p\u003e \u003cp\u003e\u003cb\u003eChapter 2 Validation of the Method of Moments For a Single Scatterer 31\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e2.1 Introduction 31\u003c\/p\u003e \u003cp\u003e2.2 Solutions of a scattering problem 31\u003c\/p\u003e \u003cp\u003e2.3 Comparison with the exact solution of a circular cylinder in free space 34\u003c\/p\u003e \u003cp\u003e2.3.1 Solution of the Helmholtz equation 35\u003c\/p\u003e \u003cp\u003e2.3.2 Dirichlet boundary conditions 37\u003c\/p\u003e \u003cp\u003e2.3.3 Neumann boundary conditions 39\u003c\/p\u003e \u003cp\u003e2.3.4 Dielectric cylinder 42\u003c\/p\u003e \u003cp\u003e2.3.5 MoM for an elliptical cylinder 45\u003c\/p\u003e \u003cp\u003e2.3.6 Numerical comparisons for a circular cylinder 47\u003c\/p\u003e \u003cp\u003e2.3.7 Conclusion 54\u003c\/p\u003e \u003cp\u003e2.4 PO approximation 55\u003c\/p\u003e \u003cp\u003e2.4.1 Formulation 55\u003c\/p\u003e \u003cp\u003e2.4.2 Applications 56\u003c\/p\u003e \u003cp\u003e2.4.3 Sea-like surface 66\u003c\/p\u003e \u003cp\u003e2.5 FB method 69\u003c\/p\u003e \u003cp\u003e2.6 Conclusion 71\u003c\/p\u003e \u003cp\u003e\u003cb\u003eChapter 3.
