Description
A multipath propagation test using the sweep frequency technique was performed over the 28-mile over-water path between Mistram Central Station and Powell Point at Eleuthera, B.W.I, during November of 1963. Large ocean reflected signals were noted. Test results show path length differences between the direct and reflected signal up to six times larger than the theoretically computed values taking into account earth curvature and 4/3 earth type of refraction corrections. The relative magnitude of the reflected signal with respect to the direct signal varied between 0.3 and 0.96.
Poor correlation between multipath phenomena and measured weather data was noted.
Application of the results of this study to improving the reliability of a frequency diversity communication link are discussed.
