Analysis of acoustic field from airborne source through air — sea interface

In this paper, the fast field program based on propagator matrix is used to model the acoustic field of airborne source in the air and underwater. The main characteristic distributions and the changing law of the airborne source radiated noise through the air-sea interface is analyzed in vertical direction at a certain distance and in level direction at a certain depth. It is of significance to further study the detection, identification and location of underwater air targets by analyzing the acoustic field of airborne radiated noise in the air and underwater provides conditions for the detection, warning, tracking, and confrontation of the air target from underwater.
