AI Technical Summary
Existing methods for generating and analyzing underwater moving targets are not applicable to underwater vertical motion characteristics, resulting in the inability to accurately obtain marine environmental information.
A Doppler multipath signal sound field model of a vertically moving sound source in shallow sea is constructed, the time-frequency domain spectrum of the received signal is obtained, and the trajectory, period and width of the interference fringes are analyzed to obtain marine environmental information.
By analyzing the interference structure of the sound field of an underwater vertically moving sound source, we can accurately obtain marine environmental information and derive a simple underwater sound field modeling method with low computational cost.
