This PFI: AIR Technology Translation project focuses on translating novel vector acoustic underwater communication research findings to fill the need for high speed communication in oceans and other underwater environments. Three quarters of the earth surface is covered with water that overlays many resources upon which our lives depend. High speed wireless underwater data communication among underwater sensors, deepwater instruments and autonomous underwater vehicles is of high importance in many applications of national interest, such as environmental ocean monitoring to predict natural disasters such as hurricanes, and offshore oil and gas drilling. However, underwater channels are highly bandlimited and the data rates of existing modems are much smaller than what is needed for effective communication and management. The project will result in a prototype underwater modem that benefits from novel vector acoustic underwater communication concepts and methods. This underwater vector modem has the unique feature of utilizing acoustic particle velocity channels for data communication, in addition to the conventional acoustic pressure channel. This feature provides the following advantages: increased data rate, improved performance, and small size modems, when compared to the leading competing underwater modems in this market space.This project addresses a number of technology gaps as it translates from research discovery toward commercial application. In the new vector acoustic and particle velocity communication paradigm, the underwater modem designer is facing new communication channels and transducers that are fundamentally different from those used in the past. Therefore, proper designs for different parts of the modem, including transducers and analog and digital transceivers will be developed. Analog electronics are supposed to interface with multi-channel transducers, whereas digital signal processing units are required to generate and demodulate multiple data streams. The personnel involved in this project, graduate and undergraduate students, will receive innovation, entrepreneurship and technology translation experiences through working at the interface of multiple disciplines such as electro-acoustic transducers, underwater acoustics, communication and signal processing hardware/software, as well as participating in an intensive boot-camp on technology entrepreneurship.The project engages Teledyne-Benthos and Kongsberg, two leading companies whose underwater modems and autonomous underwater vehicles are sold worldwide, to assist in at-sea testing of the prototype modem developed in this technology translation effort from research discovery toward commercial reality. Development of the vector acoustic high speed modem prototype will eventually allow the growth of many underwater systems and businesses whose operations have been constrained by low wireless data rates or very expensive undersea cables.

该PFI：AIR技术翻译项目专注于翻译新颖的矢量水声通信研究成果，以满足海洋和其他水下环境中高速通信的需求。地球表面的四分之三覆盖着水，水覆盖着我们赖以生存的许多资源。水下传感器、深水仪器和自主水下航行器之间的高速无线水下数据通信在许多国家利益的应用中具有高度重要性，例如用于预测飓风等自然灾害的海洋环境监测以及海上石油和天然气钻探。然而，水下信道是高度带宽受限的，并且现有调制解调器的数据速率远小于有效通信和管理所需的速率。该项目将产生一个原型水下调制解调器，受益于新的矢量声学水下通信概念和方法。这种水下矢量调制解调器的独特之处在于，除了传统的声压信道外，还利用了声质点速度信道进行数据通信。与市场上领先的水下调制解调器相比，该功能具有以下优势：提高数据速率、改善性能和小型调制解调器。该项目解决了从研究发现到商业应用的许多技术差距。在新的矢量声学和粒子速度通信模式中，水下调制解调器设计者面临着与过去使用的通信信道和换能器根本不同的新的通信信道和换能器。因此，调制解调器的不同部分，包括传感器和模拟和数字收发器的适当设计将被开发。模拟电子设备应该与多通道传感器接口，而数字信号处理单元需要生成和解调多个数据流。参与该项目的人员，研究生和本科生，将通过在电声换能器，水下声学，通信和信号处理硬件/软件等多个学科的接口工作，以及参加技术创业的密集训练营，获得创新，创业和技术翻译经验。该项目涉及Teledyne-Benthos和孔斯贝格，两家领先的公司，其水下调制解调器和自主水下航行器销往世界各地，以协助在海上测试的原型调制解调器开发的这项技术翻译工作，从研究发现走向商业现实。矢量声学高速调制解调器原型的开发最终将允许许多水下系统和业务的增长，这些系统和业务的运营受到低无线数据速率或非常昂贵的海底电缆的限制。
