Ultrafast laser technology offers compelling capabilities for national defense, state-of-the-art health care, and the materials processing industry. The development of this technology into commercial form factor hardware has been limited mostly by the size, cost, complexity, and/or pulse energy limitations of current ultrafast laser systems. Optical fiber based ultrafast lasers have dramatically d ...

The Large N ASW problem can be summarized as pervasive short-range sensors with limited communication capabilities. The driving questions are how are false alarms controlled-not necessarily from an individual sensor node, but from the overallfield-performance of individual sensor nodes, the amount of information and frequency of communication. From its inception, distributed detection has produc ...

"The overall goal of this Phase II STTR proposal is to demonstrate the capability of Naval surface and aircraft-based radars to detect and track marine mammals at representative encounter geometries. There are two major components to the proposed work: 1) acomprehensive land-based demonstration and validation experiment, using a suitable GFE radar, against humpback whales off of the coastline of H ...

The goal of this Phase I STTR proposal is to quantify the necessary hardware and processing requirements to enable a ship-based radar system to automatically detect and track whales on the ocean surface at distances of 5 kilometers or more for the purposeof collision avoidance. Long standoff detection and tracking is crucial to collision avoidance since large ships, such as commercial oil tankers, ...

The program objective is to develop and evaluate a prototype spectral polarimeter that could be used as an ISR sensor package on organic UAVs. The sensor employs advanced, visible-band technology to support littoral-zone warfare mission products, such asoceanographic characterization in VSW, including the surf; detection and characterization of stealthy or intrinsically low-contrast targets such ...

Pure oxygen is usually produced through air separation and is primarily stored as a liquid or compressed gas. Generation and storage of oxygen for use in fuel cells in self-contained underwater vehicles is particularly difficult due to the absence of airand the need to limit space and weight. There is a need for development of a dense controllable oxygen source for such applications. An alterna ...

Undersea sensors require means of transporting data to an end-user. Acoustic modem networks are being developed for this purpose, but they are limited by battery power, network priorities, and requirements for clandestine operations. We propose a systemsapproach to reducing the impact on the network of moving large volumes of data, using both low rate and high rate acoustic telemetry, combined w ...

A sensor has data to send to a human observer. In the present case the sensor is a camera, and the data consists of an image. When commanded to do so, the image is heavily compressed, passed to the modem, and sent by robust, low data rate acommsgateway, then to the observer. The sensor system retains the uncompressed image in a file. If the observer finds the (compressed/decompressed) image to ...
