The Influence of Emitter and Receiver Motion on Acoustic Coherence in Shallow Water

This paper is aimed at studying the source and receiver motion effects on the energy and correlation characteristics of the acoustic field in shallow water. The statistical analysis is based on the radiation transport equation for the mutual coherence function (MCF) of the multimodal Doppler-shifted field. A general computer program has been elaborated to implement this theory for rough surface scattering by fully developed wind seas. Calculations of the expected total average acoustic intensity and two-point coherence function are presented.
