This proposal addresses the development of a Command Post and Acoustic Listening Posts for performing detection and automatic geo-location and classification of transient acoustic sounds associated with the firing of weapons, especially rockets, mortars, and artillery and the corresponding munitions impacts. Key components of the system are rugged low-noise infrasound sensors, state-of-the-art aco ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

THE SAFETY OF THE FLYING PLATE DETONATOR IS KEY TO ITS USE IN IN-LINE FUZES. THE MAIN ADVANTAGE OF THE FLYING PLATE DETONATOR IS ONE OF ITS ADVANTAGES FROM A SAFETY VIEWPOINT; A SUBSTANTIAL AMOUNT OF ELECTRICAL ENERGY, ON THE ORDER OF A JOULE, MUST BE DELIVERED TO THE BRIDGE IN LESS THAN A MICROSECOND BEFORE THE UNIT WILL FIRE. THE FLYING PLATE DETONATOR, HOWEVER, HAS CHANGED LITTLE SINCE ITS ORIG ...

This project team will fully develop and test AlphaBear 2, a vocabulary learning game for grade 4 to 7 students. Vocabulary is a prerequisite for academic success, as it is linked to stronger performance across academic subjects and improved reading comprehension. It is more difficult for students to participate in educational activities without understanding the key vocabulary associated with tha ...

THE ARS-9 PRIMARY SURVEILLANCE RADAR HAS A DIGITAL OUTPUT INSTEAD OF THE ANALOG OUTPUT OF IT'S PREDECESSORS. THE COMPUTER AND DISPLAYS EQUIPMENT FOR NAVAL AIR TRAFFIC CONTROL COMPUTER NEEDS DIFFERENT DATA THAN THE ASR-9, NOW SUPPLIES. AN INTERFACE WILL BE DESIGNED THAT WILL TAKE THE OUTPUT OF THE ASR-9 EITHER FROM MODEM OR FIBER OPTICK LINK OR MICROWAVE LINK OR ON-SITE ATTACHMENT AND CONVERT FOR T ...

A SCANNING, PULSED DIODE LASER DOPPLER VELOCIMETER (DLDV/SP) WILL BE DEVELOPED FOR FLOW MEASUREMENTS IN AIR AND WATER, PARTICULARY COASTAL WATERS AND THE MARINE ATMOSPHERIC BOUNDARY LAYER. THE DLDV/SP, BASED ON A FIELD-PROVEN DLDV FOR OCEAN DEPLOYMENT UNDER ICE FLOWS, WILL BE DESIGNED FOR ON-AXIS BACKSCATTER OPERATION. IN A PULSED MODE, THE DIODE LASER WILL GENERATE INSTANTANEOUS LASER POWER IN TH ...

IN DEVELOPMENT OF COAL-BASED ENERGY SYSTEMS, THERE IS AN ACUTE NEED FOR INSTRUMENTATION CAPABLE OF MEASURING FLOW RATES OF SOLIDS AND GAS IN GAS-SOLID SUSPENSIONS UNDER HIGH TEMPERATURE (UP TO 1700 DEGREE FAHRENHEIT) AND HIGH PRESSURE (UP TO 100 ATM) CONDITIONS. SEVERAL INSTRUMENTATION CONCEPTS HAVE BEEN OR ARE CURRENTLY UNDER STUDY (I.E., SONIC DOPPLER METERS, CORRELATION METERS, CAPACITIVE TRANS ...

Design and analyze a new approach for a compact integrated laser/modulator suitable for high performance Military RF/photonic links. Novel design and packaging techniques including hybrid integration of narrow-linewidth, low-RIN high-power laser and a wideband LiNbO3 modulator to form a compact analog optical transmitter capable of high performance, operational over a widetemperature range.

There is a growing need to fabricate visibly-opaque, infrared-transparent, high-optical-quality optics that conform to an aircraft’s outer moldline shape to reduce drag. However, fabrication of such free-form and aspheric infrared (IR) optics has proven challenging. The current fabrication bottleneck is in the speed and precision of measuring the optical figure and transmitted wavefront error fo ...

There is a growing need to fabricate high-optical-quality optics that conform to an aircraft’s outer moldline shape to reduce drag. However, fabrication of such free-form and aspheric optics has proven challenging. The current fabrication bottleneck is in the speed and precision of performing metrology of the optical surfaces because traditional interferometric techniques are not applicable. To ...
