The Ka-/Q-band satellite systems offer potential for transportable and mobile communications through the effective use of the wide bandwidths available while requiring that adequate linearity performance be maintained. In environments where size and power conservation is of high importance, power consumption and heat dissipation in the power amplifier (PA) must be minimized. However, it is widely ...

TUI proposes to complete the development of two novel technologies that will enable pico-satellites in LEO to efficiently close the link with standard issue handheld radios on the ground. The first technology is a dual-band software-defined radio (SDR) that will provide UHF SATCOM to soldiers on the ground and a unified S-band link for backhaul and spacecraft command and control. SDR-based process ...

The objective of this project is to develop novel wireless methods and related devices for pre-fire powering of munitions capacitors and/or super-capacitors and establishing one-way or two-way data transfer link to load firing information as well as health monitoring and the like. In the proposed novel concepts, the means of transferring power into the munitions housing as well as establishing dat ...

This DoD ARO SBIR 2012 Phase II Project is aimed at the development of a micro-optical ultra-sensitive, room temperature detector for the far infrared (FIR) and terahertz (THz) bands of electromagnetic radiation. The sensor relies on monitoring optical resonances commonly known as Whispering Gallery Modes (WGM) of dielectric micro cavities. In Phase I, an operational model for this WGM radiation ...

Accurate flow calculation is crucial to the development and support of air platforms, and CFD has been successful at predicting aerodynamic performance for a variety of flows. The accuracy of CFD is governed by the quality of the surface mesh, and much work has been undertaken to automatically generate surface grids from CAD. Unfortunately, quality is quantified in terms of conformance to the su ...

Existing sensors and algorithms have the potential for protecting Unmanned Ground Vehicles (UGVs) from impending collisions, rollovers, and loss of control and for warning and assisting drivers of manned vehicles of these same potential occurrences. However, more effort is needed to develop, refine, and combine existing methods so they are reliable and run in real-time on real hardware. In this ph ...

TUI proposes to develop the Remote Anchoring Module (RAM), a launch-able anchoring system that can quickly set an anchor and tagline at a remote location without the need for manual emplacement. The RAM device will enable Army Combat Service Support engineers to rapidly, safely, and reliably accomplish anchorage of Improved Ribbon Bridges (IRB) and secure cables for improvised rope bridges. The ...

Power system upgrades for next generation ground combat vehicles require technology advances such as higher operating temperature, greater power density, and increased functionality. Silicon Carbide (SiC) based power electronic devices offer advantages over silicon devices, especially for high voltage buses, and Creare is currently developing a SiC based 12 channel, +/ 300 VDC Solid State Electric ...

Small unmanned aerial systems (UAS) are a critical element in current military operations, and their use will increase substantially in the future. The propulsion system is a key design constraint in any UAS, and current small gas turbines for these vehicles are limited by the conventional oil-lubricated rolling element bearings used to suspend their high-speed rotating assemblies. Gas-lubricated ...

Effective Army-scale mobility predictions in austere environments require knowledge of soil strength conditions at high spatial resolution (100 m or less). Knowledge of the battlespace is greatly hindered because available weather-scale near-surface soil moisture data, a primary indicator of soil strength, is limited by its coarse spatial resolution (125 km). Moreover, there are no adequate method ...
