Abstract : With the rapid development of marine science and technology and the needs of offshore operations, the study of offshore communication networks is particularly important. This study addresses the communication and perception challenges posed by the complexity and variability of the marine environment and the mobility of ships, aiming to improve the performance of offshore operations. By constructing an integrated ship-based base station model at the power level and conducting exhaustive data validation and simulation analyses, it is found that there is a linear relationship between the signal-to-noise ratio (SCNR) and the probability of detection, and that the probability of detection increases with the increase of SCNR. In multi-user real-world scenarios, the shipborne ISAC base station needs to make a trade-off between communication and sensing functions to meet different SCNR requirements. By optimising the trajectory and power allocation of shipborne ISAC, this study successfully improves the communication rate and sensing performance, which further enhances the efficiency and safety of marine operations. This study is of great significance to the development of marine science and technology and provides a solid foundation for further research and application of maritime communication networks.
