This proposal details an approach for coupling radio channel propagation models with models of the radio frequency electronics in a transceiver to allow simulation of bi-directional channel estimation in a wireless communication system. The proposed efforts focus on exploiting the reciprocal nature of the electromagnetic propagation to reduce overhead necessary for channel feedback or to enable es ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...

Compositex proposes to develop and demonstrate of a simple, low cost, high-performance chemical propulsion system for very small spacecraft sizes of 1 to 10 kilograms (nanosatellites). This system combines the ISP performance of a bipropellant system withthe simplicity and ease of operation of a monopropellant system. When compared to today's operational vehicle propulsion systems, it offers impro ...

Current microelectronics relies on silicon substrate, ceramic packaging and fiber glass circuit board, devices built using this technology is costly and not flexible. Although foils (such as polyimide or steel) promised to address flexibility, they have tobe very thin. Sarcos has been working on a revolutionary technology that will enable electronic devices to be fabricated on filamentary and elon ...
