MEASUREMENT OF COMPLEX NATURAL RESONANCES OF TARGETS IN FREE SPACE AND LOSSY MEDIA

Full Article PDF (326 KB)

Abstract:
The scattered fields of a number of targets in free space are measured. Their complex natural resonances are extracted from the late time responses, using the generalized pencil-of-function method. The complex natural resonances, as the targets are immersed in a lossy medium, are investigated using Baum's transform. The results of the complex natural resonances for various targets are expected to be utilized for target identification.
