dc.description.abstractScattering by rain in addition to inducing attenuation and depolarization in satellite links can create intersystem interference. This type of interference was investigated extensively in the 1970's for terrestrial links, but little has been done to study its effects on modern and future satellite links. This thesis reports on studies of the potential interference created by the scattering of an uplink signal into an adjacent satellite and the inverse case where a downlink signal is scattered into the earth station of an adjacent satellite system. The thesis describes the rain medium in a way which emphasizes the computation of the needed single-drop scattering coefficients using the extended boundary condition method (EBCM). The development of the experimental and theoretical study of rain scattering interference is then reviewed. Three computation methods for the interfering power are presented and compared. The first one, based on the radiative transfer equation, includes multiple scattering considerations, while the two other techniques take only the first order multiple scattering into account. The impact of such interference is then studied and an experiment involving the OLYMPUS and ACTS spacecraft is proposed.en
