Mobile Broadband Waveform Prediction Based on BELLHOP Model

摘要

To solve the problem of broadband signal waveform prediction under mobile underwater acoustic channel, mobile broadband propagation model based on ray model and a waveform prediction method based on BELLHOP model is established. The model takes the frequency-dependent propagation loss and non-uniform Doppler effect into account. The principle of this prediction method and the anechoic tank experiment's results are discussed in this paper. Anechoic tank experiment's results show that the waveform predicted by the method proposed in this paper is much more similar to real waveform than traditional method.
