Interference of Arrivals in Continuous Wave Transmission Experiments.

Abstract

The emissions of sound energy in each of the ray paths leave the source at different angles. The frequencies of the signal traveling in these paths are different by the amount of their Doppler shift. The fluctuations of the received signal are caused by the interference of signals traveling by different paths. (Author)
