Determining the scattering properties of small boats on a rough sea surface is a problem of high importance to the Navy. Due to the conducting nature of the surrounding water, the scattering signature of the boat cannot be determined just from a geometrical model in vacuum, but requires the simulation of its environment as well. The resulting simulations require large amounts of memory and computi ...

As Joint Counter Radio Frequency IED Electronic Warfare (JCREW) technology becomes increasingly prolific in military applications for ground forces, there is a corresponding requirement to develop antenna systems that accommodate present and foreseeable integration and performance challenges for these systems. With new ground vehicles, like the multiple different configurations of the MRAP, contin ...

As modern battlefield scenarios require increasingly greater radio frequency (RF) capabilities from US Army ground vehicles, there is a corresponding requirement to develop antenna systems that ensure the mutual interoperability of these functions. Currently, there is an urgent requirement to address this challenge for two essential RF capabilities: communications and electronic warfare (EW). Comm ...

The Navy Unmanned Combat Air System (N-UCAS) is a carrier-based, autonomous combat air vehicle designed to conduct long-endurance strike and ISR operational missions. Due to its very nature, the N-UCAS requires the ability to perform precision navigation in a variety of roles. To accomplish this, a commercial differential GPS (DGPS) augmentation service is used, improving precision but failing to ...

The goal of the project is to optimize the manufacturing processes used to fabricate complex aluminum alloy extrusions used in the Flexible Infrastructure (FI) systems. Various configurations of track have been fabricated to fill different functions in the FI system. The track is fabricated from a near net shaped extrusion. Holes are drilled into the slot on the top of the extrusion to provide an ...

Ultracold atoms have shown great potential in precision time keeping as well as in numerous sensing applications such as high sensitivity magnetometry, precision low-drift inertial navigation, and precision gravitational sensing. Most of the pioneering work related to the use of ultracold atoms for these applications has been done on full-sized experimental units that currently occupy entire unive ...

Current robotic MTRS EOD removal platforms have great difficulty dealing with buried EODs because their small size is insufficient to support the necessary excavation tools. Vecna Technologies, Inc. proposes a novel solution in our mechanically actuated pneumatic impact digger. The digger''s hammer chisel is mechanically actuated by pressing its tip against a surface; an innovative pneumatic shutt ...

The Navy’s Next Generation Integrated Power System (NGIPS) Roadmap depends on the conversion of medium voltage AC (4160 – 13.8KV) to DC for shipboard electrical distribution systems. Satcon’s medium voltage AC to DC converter topology supports the NGIPS architecture, allowing for galvanic isolation to provide ground fault isolation without the size and weight penalty of 60Hz transformers and ...

Aerospace optical sensor and communications applications can be performance-limited by the pointing system. Such applications include interceptor seekers and UAV LADAR turrets. These systems can benefit from the improved performance of this program’s FO15-61-BE fine-steering mirror (FSM). A miniaturized flexure suspension, enhanced actuator efficiency (acceleration-per-current) and augmented des ...

A tremendous need exists for intelligent agents that can be created and edited without resorting to intensive knowledge engineering and programming, and which exhibit believable and variable behavior in the training contexts in which they are deployed. This proposal describes a novel method for creating and editing intelligent agents’ behavior based on using instance-based modelin ...
