    • An oceanographic sampling system includes two or more underwater vehicles disposed in an array and an array controller for controlling the array of underwater vehicles as data is acquired. Each underwater vehicle includes a propulsion system for moving the underwater vehicle independently of the other underwater vehicles, a sensor for sensing an ocean parameter and providing sensor data representative of the ocean parameter as the underwater vehicle moves, a navigation subsystem for determining position data representative of the position of the underwater vehicle as the sensor data is acquired and a synchronizing subsystem for time synchronizing the sensor data and the position data acquired by the underwater vehicle with sensor data and position data acquired by other underwater vehicles. The array of underwater vehicles may function as a large aperture phased array, and phased array analysis techniques may be applied to the time-synchronized sensor data and position data.

    • An adaptive oceanographic sampling system includes several stationary acoustic tomography units distributed in an ocean volume, a processing and control system and at least one underwater vehicle movable within the ocean volume. Each of the acoustic tomography units includes an acoustic source for transmitting acoustic energy in the ocean volume, a receiver array for generating acoustic tomography data in response to received acoustic energy and a transmitter for transmitting the acoustic tomography data. The acoustic tomography data represents an ocean characteristic in the ocean volume. The processing and control system analyzes the acoustic tomography data and determines a region of interest within the ocean volume. The processing and control system then directs the underwater vehicle to move to the region of interest. The underwater vehicle includes a sensor for sensing an ocean parameter and providing sensor data representative of the ocean parameter in the region of interest. The underwater vehicle may include an acoustic source for transmitting acoustic energy to the receiver array of at least one of the acoustic tomography units.
    • 适应性海洋学采样系统包括分布在海洋体积中的几个固定声学断层摄影单元,处理和控制系统以及在海洋体积内可移动的至少一个水下航行器。 每个声学断层摄影单元包括用于传播海洋体积中的声能的声源,用于响应于接收到的声能产生声学断层摄影数据的接收器阵列和用于发射声学断层摄影数据的发射器。 声学断层扫描数据表示海洋体积中的海洋特征。 处理和控制系统分析声学断层摄影数据并确定海洋体积内的感兴趣区域。 然后,处理和控制系统引导水下航行器移动到感兴趣的区域。 水下航行器包括用于感测海洋参数并提供表示感兴趣区域中的海洋参数的传感器数据的传感器。 水下航行器可以包括用于将声能传递到至少一个声层析成像单元的接收器阵列的声源。
