About This Book

Radar Propagation and Scattering in a Complex Maritime Environment addresses advanced numerical techniques used to significantly reduce the complexity and memory requirement for solving the linear system that results from the discretization of the boundary integral equations by the Method of Moments (MoM). Typically, the problem of the VHF wave scattering from an object above a rough sea surface in a ducting environment is investigated as is the HF radar propagation above the Earth in the presence of islands. Along with these topics, the book also covers rapid asymptotic theories, which are derived and compared with references methods based on the MoM.

  • Presents tactics on scattering from both rough surfaces and near a rough surface
  • Discusses radar propagation in ducting environments
  • Includes numerical techniques to accelerate MoM

1.1 Introduction

The study of the wave scattering from rough surfaces is a subject of great interest. The applications of such research concern many areas such as remote sensing, radar surveillance, optics and ocean acoustics.
The well-known method of moments (MoM) [HAR 68, TSA 00, BOU 13b] is a way of solving rigorously the scattering problem by converting the boundary integral equations (BIEs) into a linear system, in which the impedance matrix mus...
