摘要
国家高度重视海洋发展,海洋科技已成为主攻方向,蕴含着巨大潜力。结合电磁波海面传播的特点,研究了基于改进SPM模型的海面视距传播模型,分析了频率选择、站址及挂高、天线类型、基站功率和接入信道格式等影响海面传播的五维根因,提出了“高低频+高矮站”组合的立体组网方案,助力海洋经济数字化转型。
The state attaches great importance to marine development.Marine science and technology has become the main direction and contains great potential.Combined with the characteristics of electromagnetic wave sea surface propagation,it studies the sea surface line of sight propagation model based on the improved SPM model,analyzes the five-dimensional factors affecting sea surface propagation,such as frequency selection,station location and hanging height,antenna type,base station power and access channel format,and puts forward the three-dimensional networking scheme of "high and low frequency +high and low stations" to help the digital transformation of marine economy.
