“…In particular, the two–level architecture facilitates the addition of new function modules. For example, currently, it is assumed that the sound velocity is constant; a ray–tracing submodule [ 39 ] can be added to the mapping simulation module to handle a depth–dependent sound velocity profile.…”

“…The sound speed profile (SSP) is an important oceanic parameter that is used in a variety of marine acoustic applications, such as underwater target identification, underwater communication, and marine environmental monitoring (Teymorian et al, 2009;Xu et al, 2013;Luo et al, 2022;Su et al, 2022;Zhan et al, 2023). The speed of sound varies significantly even in adjacent areas of the sea due to the complexity and variability of the marine environment.…”

“…The observations are limited by heights in [12], which offers an altitude constrained source localisation utilising Time Difference of Arrival, FDOA, and differential Doppler rate. The methods of joint TDOA and FDOA localization, passive DOA multiple sensor networks for mobile targets, and multiple sources are presented in [13], [14] and [15] respectively. However, they do not take into account receivers mounted on multiplatform devices, which can be stationary or mobile, and the method is computationally intensive.…”
