The capability to gather, analyze, and integrate vast amount of information from diverse data resources in various heterogeneous types and forms, and to distill from them the valuable intelligence leads or cohesions with respect to command and control decisions has become the top priority for U.S. military commanders. Correspondingly, inference mechanisms of automated systems must be empowered wi ...

Unmanned Aerial Vehicles (UAVs) use has increased significantly, from rudimentary reconnaissance to complex missions. In the process of becoming smarter, UAVs have also become larger, more complex, and a lot more expensive. An alternative to the complex and costly UAV model is a new paradigm employing multiple, small or mini-UAVs, that operate in virtual swarms to achieve the complex objectives of ...

Spatial processing for Navy arrays has been designed in nearly all cases based on the a horizontally propagating plane wave model, the underlying assumption being that energy arrives from far field targets as a superposition of free field traveling waves at frequencies determined by the target signature. For most situations this model has been considered "good enough", particularly in deep water ...

This STTR provides the Navy with a unique opportunity to fundamentally change the way ship design and analysis is accomplished by defining in Phase I the tools and computational infrastructure required to integrate selected individual specialty design and analysis tools into an overall Naval Engineering Analysis Tool (NEAT). NEAT, when mature has the potential to significantly reduce the design a ...

Submarines require a suite of antennas for communications, navigation, and identification of Friend or Foe (IFF). As compared to surface ship antennas, submarine antennas are unique in design, shape, materials, and performance due to space and weight limitations often in extreme environmental conditions. Under this effort, we propose a new class of more capable communication and data reception ape ...

Determining a geo-reference of an underwater object is a critical requirement for marine applications such as mine-hunting and marine surveying. Although a GPS fix can be obtained at the surface, the watch circle of a tether connecting a surface and underwater body can impose positional errors that are far greater than GPS errors. Here we propose to develop a technology to automatically determin ...

Localizing low frequency noise sources in shallow water using a horizontal array is complicated by waveguide dispersion and maneuverability constraints. If the dispersive properties of the sound propagation channel are well known, waveguide effects can be used advantageously for the purpose of localizing sources without requiring a relative change in bearing to the target. Here we propose to inve ...

Under this STTR Phase I program, we propose to develop and demonstrate dual-use Reconfigurable Electrical Power System (REPS) technology that will provide the intelligence and capability to automatically and dynamically reconfigure naval and commercial marine shipboard power systems (SPSs) while maintaining uninterrupted power to vital and sensitive loads. The proposed approach includes an intelli ...

Existing battery based energy storage systems are not suited for short duration, high cycle life, deep discharge, and small required size applications. Ultra/super capacitors (UC) are limited by some of the same issues as batteries, i.e. cycle life limitations, disposal, and continue to remain at a much higher cost than batteries. Flywheels can cost effectively fill the short duration, high cycl ...

Energy-on-target is maximized in optics and ocean acoustics by transmitting a time-reversed (spectral phase conjugated) version of received data at each array element or subarray. This process uses an unknown propagation channel as its own space-time matched filter to implement a RAKE receiver at the target location. (A RAKE receiver passes data through a filter that is matched to the channel im ...
