Abstract

Research was done to investigate the effects of building blockage on signal propagation using the uniform theory of diffraction (UTD) and two models were developed. The first was that of a mobile receiver behind a single row of buildings as a low Earth orbiting (LEO) satellite passed overhead from horizon to horizon transmitting a signal in the L-band. The second model placed a satellite in a geostationary (GEO) orbit transmitting at Ka-band. The mobile would then have a fixed elevation angle to the satellite, but with the path of propagation obstructed. Included rays were: direct, building reflected, ground reflected, building diffracted, and various combinations thereof
