An asymptotic model based on the parabolic wave equation is considered. This latter is solved using a fast and memory-efficient wavelet-based method. The roughness effects of the sea are introduced through a hybrid approach. Numerical experiments (in X-band) are provided to highlight the advantages of the wavelet-based method in the context of maritime propagation. %G English %2 https://hal.science/hal-03822316/document %2 https://hal.science/hal-03822316/file/AES_summary.pdf %L hal-03822316 %U https://hal.science/hal-03822316 %~ UNIV-BREST %~ INSTITUT-TELECOM %~ ENSTA-BRETAGNE %~ CNRS %~ UNIV-UBS %~ ENSTA-BRETAGNE-STIC %~ ENIB %~ LAB-STICC %~ INSTITUTS-TELECOM %~ LAB-STICC_PIM %~ LAB-STICC_SYPH
