海底声学参数反演问题近年来已经成为水声界的研究热点之一。论文针对不同的海底模型和海底参数提出了两种反演方法。浅海多途效应导致声场在距离‐频率平面形成干涉谱，利用距离域干涉谱提取出干涉准周期作为反演匹配物理量，提出一种基于无限均匀沉积层海底模型的海底反演方法。针对倾斜海底，提出一种基于特征声线传播时间的海底反演方法。

Underwater acoustic association pays many attentions to the inversion of sea‐bottom acoustics parameters in recent years .This paper puts forward two kinds of inversion methods about different sea‐bottom model and sea‐bottom pa‐rameters .Multipath propagation in a shallow‐water environment leads to coherent structure in the received field ,both spa‐tially and temporally .In this paper ,using range domain interference spectrum extraction cycle as a matching physical quanti‐ties ,a seafloor parameters inversion method is put forward .With inclined seafloor ,another seafloor parameters inversion method based on ray travel time is also put forward .
