Award Data

Sophisticated radar antennas such as an active electronically scanned aperture (AESA) are used to support acquisition and tracking in multiple modes over wide bandwidths, monopulse tracking, and Sense and Avoid RADAR (SAA) for UAV applications. These multi-function radar systems are small but require a considerable amount of power, which in turn produces a significant amount of heat. For these sys ...

Ship defense requires 100 kW-1MW near diffraction-limited lasers with optimal wavelength and temporal format. Laser efficiency, beam quality, atmospheric transmission, thermal-blooming, and target interactions must be taken into account. Navy efforts to date have focused principally on the free electron laser (FEL) to fulfill this need due to the wide wavelength tuning range and projected high e ...

Hypersonic flight induces severe heat loads into airframe, control surfaces and internal assemblies. Thermal protection system (TPS) insulation materials must: be stable beyond 1200°C, be compact, resist evaporation and erosion/oxidation, and have low thermal diffusivity to limit heat transfer to support structures and internal electronics. There is a need for the reduction of insulation volumes ...

STILMANs Linguistic Geometry, Real-time Adversarial Intelligence and Decision-making (LG-RAID) Technology combined with Hypergame technology will improve tactical mission planning and weapon-target pairing within complex strategic and tactical environments. This will improve mission planning and execution of single/multi-ship task groups engaging complex/futuristic threats by improving situational ...

In the Phase II effort, CEI will develop a state-of-the-art, ruggedized, Direct Band Pass, Under-sampled, Analog-to-Digital Converter (DBPU ADC) receiver targeted for the AN/SPS 49A(V) (SPS-49) search radar as part of the SPS-49 technical refresh with relevance to other applications as well. The DBPU ADC will directly replace the multi-step Intermediate Frequency (IF) analog conversion with direct ...

We propose to further develop the computer vision system created in Phase I of this project, and to adapt it to the area of underwater mine detection. Adaptation to the new environment is anticipated to be relatively straightforward, as our neural network approach has been shown to generalize well to very different circumstances after retraining. This approach allows for natural integration of mul ...

Heureka will develop and integrate powerful artificial intelligence (AI) tools into the Aegis defect management process. These tools will vastly improve Aegis operational readiness and save at least $7M per year in program costs. Two new tools will be developed. An AI-based tool called TurboTOR will meet critical needs identified during Phase I for improving change request specificity and reducing ...

Under this proposed effort, NAVSYS will leverage our expertise with developing ultra-low power GPS solutions to develop a software GPS receiver solution that can be embedded into military software defined radios (SDR) for handheld, unattended sensors and weapon applications. The objective of this effort is to develop a lightweight GPS application “GPS-Lite” which is capable of performing PPS G ...

In Phase I SPEC completed fabrication of a novel new instrument, the 3V-CPI, which makes high-speed size-distribution measurements and records high-resolution digital images of cloud particles. Also in Phase I SPEC continued to develop and improve software modules used to analyze 3V-CPI data. In Phase II SPEC anticipates working closely with the National Center for Atmospheric Research (NCAR) Rese ...

Batteries with multi-electron redox materials offer promise for increased performance relative to state of the art lithium-ion batteries. Lithium-sulfur (Li-S) batteries have two electron cathode materials (in addition to a lithium metal anode) and better than two times the specific energy of Li-ion batteries.However, several issues have prevented Li-S batteries from becoming more commercially via ...
