Research Abstract

We pursued the following two subjects as described in the application form.
The first subject is evaluation of scattering cross-sections of random media containing many dielectric particles and of reduction of target detection resolution due to random media. The Kyushu University(KU) group renewed a radiative transfer equation by using a method of evaluating the effective dielectric constants of random media, method which is based on a multiple scattering theory developed by the KU group. The renewal is based on derivation process of the University of Washington(UW) group in a dense random medium. The numerical analysis of the radiative transfer equation makes clear the characteristics of average polarization degree of scattered waves and shows that the evaluation of scattering cross-sections of random media depends largely on methods for evaluating the effective dielectric constants of random media. The subject on reduction of target detection resolution is intensively studied by the UW roup by using computer simulation and controlled experiment. The research results are reported in journals and proceedings of international symposia.
The second subject is to present imaging methods based on the results of the first subject and to evaluate the validity of the methods. The KU group tried to develop a space fi1tering technique in order to recover the loss of phase information and the UW group tried to develop a technique using pulse scattering and space or angle correlation.
Their research results will be reported in journals and proceedings of international symposia. Both groups point out that the combination of each technique plays an important role in imaging in biological-environmental random media.
