Study on Correlation Processing for Acoustic vector Signals in Underwater Sound Channel

摘要

The correlation processing for acoustic scalar signal has been widely used in underwater signal processing. In this paper, the correlation processing for acoustic vector signal is studied. First, a vector impulse response function was introduced to characterize the transmission of the acoustic vector signal in the underwater sound channel. Second, a modified replica correlation algorithm for acoustic vector signals was derived according to the vector impulse response function and it was used for signal detection and multipath extraction in underwater sound channel. The feasibility of this method is validated through simulation study and experimental data processing.
