摘要
Abstract
High frequency(HF)sky-wave propagation is limited by the working frequency,and the antenna size meeting high gain and adapting to high sea conditions is large,so the application scenario is seriously limited.For the demand of cross-domain long-distance transmission of far-sea science detection information,a cross-domain buoy communication technology integrating HF communication,underwater acoustic communication and unmanned buoy characteristic was proposed.The composition and working principle of far-sea cross-domain transmission buoy devices were introduced,and the working flow was designed.Through the design of a flexible HF antenna with variable length and integrated power amplifier components for water cooling and heat dissipation,the advantages of high antenna gain,strong adaptation to sea conditions,and cross-medium transmission were ensured.The simulation analysis shows that the proposed communication method can effectively guarantee the communication effect and achieve reliable cross-domain long-distance communication of HF signals in high sea conditions and complex interference environments,providing certain technical support for the development of maritime long-distance cross-domain communication.关键词
