U.S. sailors train for anti-missile defense via a video game. Team play is said to improve collaboration skills, and the exposure to different threat environments gives novices a rapid introduction to threat assessment, tactics and decision-making.
Researchers develop a proof-of-concept lidar prototype that improves the speed and accuracy of ocean scans and allows the collection and transmission of data in real time for production of high-resolution 3-D images.
Target-tracking systems rely on algorithms that plot the movement, speed and position of threats, while filtering background noise that obscures this data or produces false alarms. Algorithms have been formulated that address most tracking needs with varying degrees of success, but it appears that no single algorithm has thus far been able to meet every tracking need, especially when it comes to distinguishing one or more dynamic targets from background noise.
The days of front-loading equipment programs with costly prototypes and field trials may be over—at least if a simulator developed by Chemring Technology Solutions (CTS) gains wide acceptance for research and development initiatives.
The U.K.-based company, whose focus is defense and security technologies, recently developed the Dismounted Close Combat (DCC) simulator, which provides a fully immersive environment for preliminary testing of concepts and prototypes.
One problem in war is that enemies do not stand still to be dispatched with one shot. Hence, the importance of hitting moving targets. Rifle practice in this area, though, is rare—even the U.S. Marine Corps falls short. This could be changing, however. The Marine Corps Warfighting Laboratory (MCWL) tested techniques for accurately engaging moving targets last month in Quantico, Va. Marines fired M-4 carbines and M-27 infantry automatic rifles at life-size plastic mannequins on tracked robots moving at 4-8 mph.
A thermocouple developed at Cambridge University in England to measure jet engine temperatures near their combustion source reduces drift by 80% at 1,200C (2,192F), and 90% at 1,300C. Drift is degradation in a sensor, typically a double-walled nickel-based thermocouple in this application, which monitors engine heat. High temperature affects the integrity of components and thus, engine maintenance and life. Most nickel-based thermocouples drift above 1,000C. This is a problem because many engines reach 1,500C.
The U.S. Navy wants to develop an onboard sensor that provides ships engaged in resupply at sea forecasts of environmental conditions, wave motions and ship movements such as pitch, heave and roll. The objective is to base materiel transfer decisions on the best available data to increase safety and efficiency. A research partnership of industry and academia, led by the Office of Naval Research (ONR) and Naval Surface Warfare Center Carderock Div., tested hardware and software last month for the Environmental and Ship Motion Forecasting (ESMF) system.
