| 英文摘要 | The acoustical properties of a sea bottom can be described using a geoacoustic (GA) model composed of several layers and is usually characterized by GA parameters such as sound speed, density, sound absorption parameter, and thickness. As the parameters are difficult to measure directly, they are often estimated using inversion methods. Although GA inversion is the most economical method to obtain the seabed acoustical parameters, the results of inversion are far from unique owing to the coupling between GA parameters. However, numerical simulations show that the model-free parameters (P, Q) can indicate the reflection characteristics of the bottom at small grazing angles. Using these parameters, the effect of bottom on propagation is concisely represented. In this paper, data from an acoustic propagation experiment in the South China Sea (SCS) are used to invert the seabed GA parameters, and based on the inverted results, it was concluded that different “effective GA parameters” have the same reflective characteristics (P, Q), regardless of the GA model being used. |
