Objective: The objective of this program is to conduct an in-depth investigation of underwater distributed antenna system, where a large number of spatially distributed underwater transducers / hydrophones are interconnected via cable or radio links. Such systems are drastically different from their terrestrial counterparts due to unique underwater channel characteristics. Field engineers have relied on engineering intuition when building such operational networks to support communication and navigation needs of autonomous underwater vehicles. However, a systematic study of such systems is lacking. This program will explore both fundamental limits and the design of practical communication algorithms for different types of traffics in such a system. Selected designs will be validated in real-world facilities with different channel conditions and system characteristics.Intellectual merit: The intellectual merit is to address realistic challenges in a unique underwater distributed antenna system, which differs from the radio counterparts due to long channel dispersion, fast channel variation, large propagation delay, and half duplex operational constraint. This program will provide a rich set of theoretical insights and practical algorithms, supported by extensive real-world validations.Broader impacts: The broader impacts are: (i) fast transition of the project outcome to practical underwater distributed antenna systems, providing tremendous benefits to various scientific and homeland security applications; (ii) involvement of graduate students in challenging research problems in the fast-growing field of underwater acoustic networks; (iii) participation of undergraduates, women and other under-represented groups, in advanced research and its practical applications.

目的：该程序的目的是对水下分布的天线系统进行深入研究，其中大量空间分布的水下换能器 /言语通过电缆或无线电链路互连。由于独特的水下通道特征，此类系统与它们的陆地都大不相同。野外工程师在建立此类运营网络以支持自动水下车辆的通信和导航需求时依靠工程直觉。但是，缺乏对此类系统的系统研究。该计划将探索基本限制和对这种系统中不同类型的贩运的实用通信算法的设计。选定的设计将在具有不同渠道条件和系统特征的现实世界中进行验证。智能优点：智力优点是在独特的水下分布式天线系统中应对现实挑战，这与无线电的挑战不同于无线电频道分散，由于长频道分散，快速通道，快速变化，大型传播延迟和半二线构成约束。该计划将提供丰富的理论见解和实用算法，并得到广泛的现实验证。BRODER的影响：更广泛的影响是：（i）将项目结果快速过渡到实用的水下分布式天线系统，为各种科学和国土安全应用提供了巨大的好处； （ii）研究生参与水下声学网络快速增长领域的挑战研究问题； （iii）在高级研究及其实际应用中，大学生，妇女和其他代表性不足的群体的参与。
