Abstract
An acoustic field model through the sediment in slight depth is presented. The method is based on the stratification of homogeneous media to simulate the geoacoustic properties in sediment environment. The acoustic field model is calculated from an acoustic array antenna which uses focalization for transmission and reception. The beam wave model includes the direct ray and all reflexion rays. Different studies in stratified media solved this problem by using a matrix formalism or a finite difference method. Here we use a binary algorithm. In a preceding study, we have valided the antenna model with experimental data in the simple case of water. The results are presented for two positions of antenna and for two sediments
