【Abstract】 To design a new buried-object detection system is important to understand the mechanism and quantity of finite acoustic beam penetration into a sandy bottom. The wavenumber integration sound model and the modeling method for finite beam based on an effective vertical source array are used to simulate the penetration of finite beam into a sandy bottom. An experiment in a pool is designed to observe the penetration of the acoustic beam, and the results are compared with the modeling. Several issues about the sound penetration experiment are discussed.更多还原
