Multipath, underwater acoustics, ray tracing, bellhop.

Understanding and building effective communication systems in underwater environments requires the use of multipath channel modelling. However, there are substantial difficulties in adequately characterising the intricate propagation behaviour of underwater acoustic channels. In order to address these issues and offer solutions for more precise multipath channel modelling, this study focuses on the use of ray tracing techniques, in particular using the BELLHOP approach. The paper begins by outlining the difficulties with multipath channel modelling in underwater acoustics, such as multipath propagation, the channel's time-varying and dispersive characteristics, and the lack of extensive measurement data. It then looks at how ray tracing methods, notably those that employ the BELLHOP approach, overcome these issues and make it possible to depict the underwater audio channel in more depth and with more realism. The ray theory-based BELLHOP method is a potent tool for modelling sound propagation in aquatic environments. It takes into account beam reflection, refraction, and scattering phenomena and enables the strength and timing of multipath arrivals. The BELLHOP approach captures the complicated multipath propagation characteristics and offers insights into the spatial and temporal properties of the underwater channel by tracking individual rays and taking into account their interactions with the environment. The BELLHOP method for ray tracing in underwater acoustic channels is covered in detail in this publication. It looks at methods for tracking rays and simulating the effects of various environmental conditions. The research also discusses difficulties in dealing with range-dependent settings, various seabed compositions, and sound speed profiles. In order to evaluate the precision and dependability of the ray tracing models, the research also provides validation procedures and comparisons with measurement data. It addresses the benefits and drawbacks of BELLHOP and normal mode approaches as well as how they might be used in different underwater communication systems. By demonstrating the power of ray tracing methods using BELLHOP and normal mode approaches
