High-power, high-efficiency, broadly-tunable coherent sources in the mid-wave infrared (MWIR, λ=3–5 μm) spectral band are coveted for applications relating to infrared (IR) countermeasures, remote chemical sensing, and free-space optical communication. MWIR sources based on optical nonlinear frequency conversion can generate broadly-tunable kilowatt-level coherent radiation over the e ...

There is a DoD need for the development of robust sensors to obtain temporally and spatially resolved surface temperature and heat flux measurements on test articles in blowdown and continuous hypersonic wind tunnels. These micro-heat flux sensors are required in order to better understand the state of the boundary layer of a hypersonic vehicle; to better understand boundary layer instabilities; a ...

The problem addressed in this effort is to automatically learn historical ephemeris space catalog time, position, and velocity entity track update error uncertainties (i.e., without track error covariances) and to automatically (e.g., without expert event labeling) produce: – unmodeled non-gravitational space catalog update flags – abnormal unmodeled catalog update flags with abnorma ...

Near-Earth space environment is hazardous to satellites. This harsh particle radiation can penetrate protective shielding, accumulate in sensitive materials and can damage even well shielded electronic components causing temporary malfunctions or a complete system/mission loss. The goal of the proposed work is to provide the Air Force with a state-of-the-art model of the outer zone energetic elect ...

Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: ...

The Phase II effort will be to clearly demonstrate the feasibility and build a prototype of a noncontact, high-quality holographic polarimetry system with pixel level depth and Mueller matrix information with a user-friendly interface to image and display this data. The measurements of each data product will be validated with trusted truth samples. The system will be reproducible and will have a d ...

The Biomagnetics Micro Dosimetry System (BMDS) program will design, model, and simulate a microdosimetry system that can measure and create a three dimensional map of weak radiofrequency signals in biological organisms. The heart of the BMDS project is the front end that delivers very sensitive, broad band measurements with high spatial resolution. The front end is a valuable tool in the investiga ...

Currently fielded multi-beam CDL systems have been developed in an ad-hoc manner consisting of a collection of poorly integrated off the shelf technologies where controllers, radios, routers, firewalls, encryptors, and antennas are bolted together to reduce time to field. Proprietary API’s, electrical interfaces, and hardware interfaces impede the success of the approach and result in a sub ...

Successful completion of this Phase II proposal will fully characterize and evaluate a material for use in RF windows on hypersonic flight vehicles. Phase II will specifically examine the materials suitability through RF testing in X, Ku, and Ka bands and at elevated temperatures to 2000°F. The desired outcome will be a material with predictable, repeatable dielectric properties over frequency ...

FIRST RF will lead the Phase II effort and will leverage the system architecture of the MAINLINE system and integrate multifunctional SiGe integrated circuits (ICs) developed by The University of California San Diego under the supervision of Prof. Gabriel Rebeiz. The SiGe devices developed during the Phase II effort will significantly reduce the power requirements of the MAINLINE system allowing f ...
