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 ...

Small Business Innovative Research (SBIR) N101-004, Air Anti-Submarine Warfare Modeling and Simulation Tool, was issued to determine the feasibility of developing an Anti-Submarine Warfare (ASW) Modeling and Simulation (M&S) tool to bridge the current gap between engineering and campaign-level tools. For this Subsequent Phase II, Sonalysts proposes to develop a FDECO Test Range Simulator (TRS) bas ...

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 ...

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 ...

THE REQUIREMENTS OF SPREAD SPECTRUM TECHNOLOGY, ACOUSTIC COMMUNICATION, AND SIGNAL SPECTRUM CODING MAKE IT NECESSARY TO INCREASE THE EFFECTIVE BANDWIDTH OF THE SONAR PROJECTOR. A UNIQUE APPROACH TO DOING THIS WITHOUT SACRIFICING THE TRANSMITTING AND RECEIVING RESPONSES OR TOTALLY REDESIGNING THE TRANSDUCER, IS TO APPLY THE TECHNIQUE OF NEGATIVE IMPEDANCE. THE MAJOR GOALS OF PHASE I WILL BE TO (1) ...

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 ...

THE OBJECTIVE OF PHAE I IS TO DETERMINE BY AN ANALYTICAL STUDY THE OPTIMUM DESIGN APPROACH, OR APPROACHES, FOR SOLID-STATE ELECTRICAL FAULT CURRENT LIMITERS FOR THE CURRENT RANGE OF 15 TO 5000 AMPERES. THE ANALYTICAL TRADEOFF STUDY WILL INCLUDE THE FOLLOWING TASKS: 1) DEFINITION OF CURRENT LIMITER REQUIREMENTS, 2) DEFINITION OF TRADEOFF ANALYSIS CRITERIA, 3) DEFINITION OF CANDIDATE CURRENT LIMITER ...

We are developing a platform for pharmacometric data analysis workflow that is much more flexible and efficient than anything else on the market. This will be accomplished by (1) developing new functions within Stan, a widely used, open-source, probabilistic programming language and Bayesian inference engine, for computationally efficient data analysis using complex differential equation models, ( ...

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.
