Contents

In this paper a frequency domain analysis of buried dielectric cylindrical targets is given. An integral equation, which is solved by Galerkin's method along with plane wave basis functions, is used to obtain the scattered field. Numerical results in the frequency as well as the time domain-via FFT-for various underground bodies in various depths are given. The results show the applicability of the method in the target identification process.

Übersicht

Die Arbeit präsentiert eine Frequenzbereichs-Analyse von unterirdischen dielektrischen, zylinderförmigen Zielen. Das gestreute Feld wird durch eine Entwicklung in ebene Wellen und die Lösung einer Integral-Gleichung mit Galerkins Verfahren gefunden. Numerische Ergebnisse im Frequenzbereich, sowie durch FFT auch im Zeitbereich, werden für eine Anzahl von Körpern in unterschiedlichen Tiefen angegeben. Die Ergebnisse zeigen die Anwendbarkeit der Methode für Ziel-Identifikationsaufgaben.
