Military operations in cold environments require warfighters utilize protective garments, such as boots, to reduce heat loss and prevent numbness, clumsiness, frostbite, and hypothermia. Current state-of-the-art flight boots do not meet extreme cold protection requirements, due to shape and size limitations imposed by restricted foot space in and around aircraft. Powered limb heating systems can i ...

AN/SSQ-53G Directional Frequency Analysis and Recording (DIFAR) sonobuoys are a critical asset to the Navy and have been in use since the 1970s. With the advancements in technology, it is now possible to miniaturize and more efficiently implement the upper portion of the sonobuoy to create space for additional sonobuoy capabilities without increasing the sonobuoy’s physical size. To address this ...

To address the need to mitigate cooperative and noncooperative in-band interference in airborne anti-submarine warfare (ASW) systems, ARiA will develop and demonstrate the feasibility of signal and information processing algorithms for mitigating various types of in-band interference. ARiA will develop and evaluate (1) model-based adaptive signal processing in space, time, and Doppler to mitigate ...

Within the increasingly contested undersea operational arena, the Navy needs a tactical and competitive advantage in undersea sensing and detection through improved situational awareness with respect to environmental parameters, such as sound speed profile (SSP) and bottom properties, that affect overall submarine sonar sensor performance. Current approaches for enhancing environmental situational ...

Large aerospace composite structures currently require autoclaves and ovens to achieve desired performance which are expensive to purchase, costly to operate, and often limit part size and production rate. Ovens and autoclaves rely on convective heating which is inefficient, consumes large amounts of energy, and can be difficult to predict. Alternative cure processes using external heaters or hot ...

To realize the full potential of autonomous systems, it is imperative that they behave safely, correctly, ethically, and legally. Providing these assurances through offline verification alone is insufficient, due to the complex and changing nature of autonomous systems. Online monitoring and corrective actions are necessary to account for uncertainties, and to increase trust between a human superv ...

To support Navy’s need for novel algorithms using improved energy clustering and association techniques to represent the spatial and Doppler distribution of active-sonar returns to improve active-sonar tracking and classification performance for the AN/SQQ-89A(V)15, ARiA will develop and demonstrate the Next-Generation Clusterer (NGC), a suite of algorithms for feature-augmented contact localiza ...

This Phase I proposal to Topic N191-022 describes BTech’s approach to develop a smaller diameter version of the ADC MK 4 Mod 1 countermeasure that will fit into a 3-inch diameter form factor. Designs of the electroacoustic transducers and tuning/matching circuits are described that enable low frequency coverage in a smaller diameter vehicle. The proposal draws on BTech’s experience with broadb ...

This Phase I proposal to Topic N191-023 describes BTech’s approach to develop a method to control depth of a 3-inch counter measure to replace legacy system that relies on a propeller. Designs and calculations are presented that support the feasibility of our proposed approach and that it will reduce energy consumption.

Next-generation munitions require new materials able to withstand extreme operational environments while maintaining RF performance. Hypersonic missiles and hyper velocity projectiles traveling in excess of Mach 4 generate surface temperatures of 1500°C or greater and may see up to 30,000g at launch. These flight vehicles still require communication, targeting, and guidance systems which must be ...
