Abstract EN
Backscattered sound waves of seabed sediments are important information carriers in seafloor detection and acoustic characteristic parameters inversion.
Most of the existing methods for estimating geoacoustic parameters are based on multiangle seabed backscattered signal processing and suitable for flat seafloor conditions with uniform sediment thickness.
This usually deviates from the real field conditions and affects the accuracy of parameter estimation.
In this paper, the sound ray propagation theory is studied and analysed under the condition of sloping seabed and uneven sediment thickness.
Based on the phased parameter array sonar system, a method of acoustic parameters estimation of the sediment under inclined seabed conditions is proposed.
The simulation results show that the new method shows good adaptability to different inclination angles of the seabed and solves the problem of accuracy of acoustic parameter estimation of the inclined seabed sediments.
The model will greatly reduce the seafloor topography requirements in the sediment acoustic parameter inversion, such as velocity, layer thickness, and acoustic impedance.
