Active Spectrum, Inc. proposes a novel, low-cost soot sensor for on-board measurement of soot emissions in diesel exhaust gases. The proposed technology is differentiated from existing method by excellent sensitivity, high specificity to carbon particulates, and robustness to fouling by accumulated soot. Potential commercial applications of the real-time sensor include diesel emissions reduction ...

The objective of this proposal is to demonstrate the feasibility of mass producing robust miniaturized, tunable narrowband preselect filters in the 500-2000 MHz bands for fielded JTRS platforms. In the 500 MHz – 2000 MHz frequency bands, we proposed a tunable 2-pole narrowband (30 MHz) preselect filter. Active Spectrum, Inc.’s filters represent a proven, significant improvement over the state ...

The proposal describes a miniaturized tunable filter technology for wideband tuning in the 500 MHz to 3 GHz bands. The filters use a novel actuator to achieve a combination of wide tuning range and high-Q of the resonant elements. The filter technology can be integrated into a small surface mount package, as described in the proposal. The technology is a major step for reducing the SWAP of front- ...

This proposed Phase II program will deliver a lightweight triple-junction solar cell that eliminates the current-matching bottleneck of current state-of-the-art InGaP/GaAs/Ge cells on Ge. This will be achieved by constructing a triple junction structure on the lattice constant of SiGe, allowing the integration of semiconductors with bandgaps that are optimized for the best possible triple-junctio ...

Agricultural row crops occupy over 200 m acres of land in the US. Decisions regarding the implementation of tillage practices in these agricultural areas have a significant effect on other environmental outcomes, including soil erosion, water quality, and carbon sequestration. In addition, the effects of tillage practices can vary due to soil type and topographic conditions. There is currently no ...

This Small Business Innovation Research (SBIR) Phase I project will use Particle Image Velocimetry wherein a sample sheet volume is illuminated by laser diodes. A high speed camera takes pictures of precipitation illuminated in the sample volume. The proposed data analysis software would use object and pattern recognition algorithms combined with statistical analysis packages to generate output da ...

This proposal will address the development of a digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray. This al

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

The design and development of scalable panel-based phased-array radars requires the high density integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current integration technologies such as system-on-a-chip (SOC), multi-chip-module-deposition (MCM-D), and system-on-package (SOP), will help miniaturizing sub-modules for various functional ...

This proposal will address the development of a wideband digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray in order to generate flexible waveforms and beams with improved performance. The technical challenge is to meet the required receiver sensitivit ...
