This book is intended for scientists and engineers working in the field of radar and computational electrodynamics.
The contents of the book is the result of the compilation of works by group of authors who rep-resent the scientific school of applied electrodynamics established in the 1960s by Professor I.V Sukharevsky within the Govorov Military Radio technical Academy.Representatives of this school studied electromagnetic wave scattering from objects of various natures in the Kharkiv Military University, United Scientific Research Institute of Ukrainian Armed Forces, and Kharkiv Ivan Kozhedub University of Air Force.
An important place that the study of radar scattering from airborne and ground objects occupies in the whole radar field predetermined the book's main content.In the first place, it was the number of generalizations of the key postulates of classical electrodynamics theory that needed to be intro-duced in order to provide grounds for the methods of radar object scattering computation developed later on.The basic results regarding development of both the electrodynamics theory and numerical computation methods are original and a represented in the first two chapters of the book.
Chapter 3, intended as a reference, is for consumers who are engineers pursuing the design of radar detection and identification algorithms with regard to airborne and ground objects.The chap-ter contains a great deal of reference material obtained by computation: circular diagrams of radar backscattering; mean and median RCS values of various objects; probability distributions of echo signal amplitude given various parameters of illumination and various kinds of underlying surface (for ground objects); and impulse responses of various airborne and ground objects given their illu-mination with wideband signals.
The book can be useful to a wide audience: scientists concerned with the development of electromagnetic wave scattering theory, computational electrodynamics specialists, as well as to radio physics engineers pursuing development of radar detection and identification algorithms of radar objects.
The authors' contributions to the book have been as follows: Chapter 1 has been written by Oleg I. Sukharevsky; Sections 2.1 through 2.3 and 2.5 are the combined work of Vitaly A. Vasilets and Oleg I. Sukharevsky; Section 2.4 has been written by Sergey V. Nechitaylo and Oleg I. Sukharevsky (except for Section 2.4.2, which has been written by Vitaly A. Vasilets and Oleg I. Sukharevsky); Chapter 3 has been written by the mutual effort of Vitaly A. Vasilets, Sergey V. Nechitaylo, Oleg I. Sukharevsky, and Valery M.Orlenko.

Professor Oleg I. Sukharevsky has worked in the field of applied mathematics and computational electrodynamics since 1972 when he received a diploma degree in computational mathematics from Kharkov Gorky State University and joined the Kharkov Govorov Military Academy of AirDefense as an engineer. Since 1977 Dr. Sukharevsky has studied and developed numerical compu-tation methods that were based on solving the two-dimensional integral equations to obtain scattering characteristics of non closed screen and antenna underframe radome. In 1983, Dr. Sukharevsky earned the candidate of technical science degree (PhD analog) from the All Union Research Institute of Radio techniques, by that time he was raised to the position of a senior researcher. Since then, he has carried on studying the scattering phenomenon and started the development of scattering theory and technique for computing radar cross section of complex objects, special emphasis being put on the objects that had surface fractures (sharp edges) and were covered (partly) with radar absorbing materials.
