Research Progress and Development Trend of Air-Sea Cross-domain Communication

At present, there is an increasing demand for real-time communication and data transmission between the air and the sea. Therefore, it is important to study robust and reliable air-sea cross-domain communication technologies. However, due to the different characteristics of the two media and the impact of harsh environments, air-sea cross-domain communication channels are complex and varied, making it difficult to smoothly pass through the air-water interface. In order to better understand the development of air-sea cross-domain communication technologies, the current research on air-sea cross-domain communication was comprehensively summarized, and its working environment and development of communication technologies were explained. The technologies were divided into two categories: air-sea cross-domain link-level direct communication and air-sea cross-domain relay communication. Then, the research status, difficulties, and proposed solutions were summarized. Finally, future research directions were discussed. The research can help to promote the development of air-sea cross-domain communication technologies.
