SARA’s PolyUrethane Millimeter-wave Imaging System (PUMIS) will image surface-metal defects through optically and acoustically “thick” coatings, such as those found on submarine exteriors, witho ...

The Autonomous Helmsman is a behavior-based controller that provides COLREGs-following autonomy for unmanned surface vessels (USVs). The Helmsman is based on the MOOS robotic architecture which hosts ...

Various approaches have been proposed for UAVs to detect and avoid collision with other aircraft. This approach detects the low-frequency sound of approaching aircraft to detect and to determine beari ...

Dynamic Bi-directional Reflectance Distribution Function (BRDF) of various solid targets (Zirconia, Aluminum and Steel) under conditions of rapid heating by a kilowatt class High Energy Laser (HEL) is ...

A continuing theme in shipboard monitoring is the need to inspect hulls of boats and submarines for signs of metal fatigue, typically manifesting as weld breaks, corrosion, and for submarines, metal-p ...

Modern bioweapon detection systems are highly accurate, but require expensive reagents to operate. To reduce costs, a less discriminate trigger system is used to signal the primary detector when a su ...

A common mission for helicopters is to move heavy loads suspended on a cable attached to a hook or winch system. During flight, the aerodynamic and inertial forces acting on the load can cause it to ...

Successful platform-integration of high power microwave (HPM) directed energy weapons (DEW) poses very demanding challenges.  Unwanted radiation (near-field and far-field) and surface currents locall ...

The system-level design of a geolocation system for detecting and locating RF emitters on a small, unmanned aerial vehicle (SUAV) will be competed. The design will include system-level design, sensor ...

Autonomous Unmanned Aerial Vehicle (UAV) participation in controlled airspace requires that the UAV behave just as a human-piloted aircraft. Forward airbases with Air Traffic Control (ATC) can be com ...
