We propose a large area low cost manufacturing process for diffraction gratings with very small line-edge-roughness (LER) and defect-free surface using self-perfection by liquefaction (SPEL) and nanoimprint lithography (NIL). The manufacturing process is capable of producing diffraction gratings covering wavelength ranging from UV to LWIR. The manufacturing process starts with making a master grat ...

MaXentric proposes to focus on a low noise, high linearity and high reliability of the downconversion chain for this effort, and especially the AlGaN/GaN HEMT low noise block downconverter. MaXentric will employ a noise cancellation design in AlGaN/GaN low noise amplifiers (LNA) to reduce the overall noise, in conjunction with optimal gate biasing and digital predistortion to enhance the overall l ...

In this proposal, C & P Technologies (C & P) offers an innovative generalized adaptive radar signal processing technique that will improve the capability of the warfighter to detect enemy combatants (dismounts) in challenging clutter environments. Radar is the sensor of choice for this persistent surveillance application because it can operate at long range, both day and night, and under a wide v ...

Under this SBIR effort, we propose to develop a system architecture that provides improved accuracy and availability under adverse conditions for networked GPS receivers operating collaboratively using a GPS Distributed Aperture Processing (GDAP) approach. The proposed collaborative approach operates by using a combination of shared GPS observations, augmented by other networked observations incl ...

The FIRST RF approach to the handheld antenna for Global Navigation Satellite Systems (GNSS) is a wide bandwidth, wide beamwidth, compact adjustable element with integrated Low Noise Amplifier (LNA). This approach uses an innovative FIRST RF design to maximize bandwidth around the GNSS 1164-1611 MHz band while minimizing volume, maintaining uniform gain, providing efficient radiation over the ful ...

Modern antenna technology makes possible the deployment of systems able to perform radar, communications, and electronic warfare functions with a single aperture. Such systems, due to demanding mission requirements and constraints, must switch among numerous modes while maintaining essential functions (e.g. air-to-air situational awareness). Therefore, radar functions that normally require extend ...

ABSTRACT: This proposal describes radar sensors and data processing algorithms that address the technology gap between NSMS and strain gage vibration surveys. The radar-based approach provides data that can be processed in the time and frequency domains to accurately track blade vibration down to very low levels and over a very wide bandwidth. The work in this project will be planned, performe ...

ABSTRACT: Optical diagnostics for combustion, such as planar laser induced fluorescence (PLIF), require high power ultraviolet (UV) laser light with high spatial quality. Fiber optic delivery of such UV light would provide the robustness needed for applications in harsh environments, for example to combustors. However, the need to deliver high intensity UV light presents challenges for convention ...

Mechanical Solutions, Inc. (MSI) is currently developing a Vibration and Physics-Based Health Management system that focuses on rotating machinery. MSI is now proposing to augment this system to also address valve health monitoring. This will require the incorporation of additional condition indicators, and the associated data acquisition and signal processing, specific to failure modes of valve ...

ABSTRACT: Fires in dry bays and engine nacelles of military aircraft present a significant hazard to aircraft survivability. The USAF is interested in reducing weight and improving performance of systems to protect these spaces. ADA Technologies, Inc. has 10 years experience developing advanced fire suppression technologies, and proposes a solution that aims a plume of clean agent directly at fir ...
