In this paper, we study sense-through-foliage target detection using ultra-wideband (UWB) radar. We propose a Discrete-Cosine-Transform (DCT)-based approach for sense-through-foliage target detection when the echo signal quality is good. We compared our approach with the ideal case when both echos are available, i.e., echos with target and without target. We also compared our approach against the...
Gulf of Mexico oil spill in 2010 has generated deep impact on the beach soil. Microwave emission and backscattering of the beach soil depend on its dielectric property which exhibits dispersion and absorption and is affected by the oil, salt, and moisture content. In this paper, we apply Ultra-WideBand (UWB) radars sensor network to perform the beach soil dielectric property studies due to the oil...
An image indexing method is presented to perform the CBIR (content based image retrieval) for about 100 different images. The method is based on the fractal framework of the PIFS (partitioned iterated function systems) widely used for image compression. The image indexing is represented through i-model features. A specific searching algorithm allows to use this representation as an indexing to retrieval...
