摘　　要：面向海洋立体信息感知中长期环境监测、目标探测、区域预警、跨介质信息中继等领域对极浅海域空海信息链路的需求,考虑极浅海域信道恶劣、潮流复杂、环境噪声严重等困难,采用直接序列扩频结合差分二进制相移键控(DS-DBPSK)的水声调制解调技术,以波浪滑翔器为平台进行水声通信、无线系统设计与整合,构建面向极浅海域水下信息支持的波浪滑翔机跨介质通信链路,并在平均深度12 m的厦门港海域开展极浅海域跨介质通信实验,验证了所设计技术方案及系统的有效性。Orienting the demand for air-sea information links in extremely shallow waters in the fields of medium-and long-term environmental monitoring, target detection, regional early warning and cross-media information relay in marine stereoscopic information perception,and considering the difficulties of poor acoustic channels,complex tidal currents and severe environmental noise in extremely shallow waters,the underwater acoustic modulation and demodulation technology of DS-DBPSK is adopted. Using the wave glider as the platform for the design and integration of underwater acoustic communication and wireless systems,the wave glider cross-media communication link for underwater information support in extremely shallow waters is built. The cross-media communication experiment in extremely shallow sea areas is carried out in the sea area of Xiamen Port with an average depth of 12m,and the effectiveness of the designed technical scheme and system has been verified.
