The objective of this research is to develop materials that replace the current generation of visible smoke formulations used by the U.S. military. In particular the materials must produce low or no flame so that they don't present a fire hazard, have relatively low toxicity, and are efficient. The efficiency is defined in a figure of merit that combines fill factor, yield factor, extinctio ...

Sensor development researchers and engineers have perpetually sought novel methods to reduce sensor size and improve performance. Continued miniaturization of sensors through micromachining has enabled novel applications and introduced new paradigms for engineered systems to interact with the world. The challenge has always been to improve performance while continually reducing size. In the curren ...

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. The proposed technique not only exhibits the statistics of voxel based obscurants, but matches real-world data as well. The main objective from Phase II efforts will be a further refinement of the flow field and particle technique of generating physically c ...

"Diesel generators provide the majority of power generation in forward operating areas, frequently operating inefficiently and requiring excessive maintenance."Right size"generator operation, energy storage, renewable energy inputs, and intelligent power management strategies can greatly reduce fuel consumption and reduce the level and frequency of maintenance. Predictive load profiling strategie ...

CFDRC proposes to develop a computational tool for transient, high-altitude events with mixed continuum and free molecular flow regimes. The proposed technology builds upon the Unified Flow Solver (UFS) previously developed by CFDRC, which will be leveraged with several new features for transient chemically reacting two-phase, gas-particle flows interacting with multiple bodies in relative motion ...

This proposed Phase II effort is a continuation of the SBIR Phase I contract (W31P4Q-13-0014) which identified several potential areas of improvement in signal processing for semi-active laser seekers in noisy, dirty-battlefield or countermeasure environments. A list of innovative processing algorithms to address these issues was down-selected to the four highest pay-off innovations: Smart Track ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

A novel signal/waveform model and signal processing algorithm suite that enhances radar systems performance, in the presence of noise and high clutter environments, and its associated discrimination capabilities is proposed. The algorithm allows for extraction of target information in range, azimuth and elevation angles while achieving very fine resolution and high accuracy. Target information at ...

Proposed research will address the phenomenology and develop a technical concept of buried IED defeat through the creation of low-frequency electromagnetic fields in the ground by the LF current injection. The technical concept will be based on creating pulsed low-frequency currents in the ground layer using either explosive or capacitor driven pulsed current source and then employing the key prin ...

This work describes an innovative approach to producing high power RF suitable for use in Directed Energy Weapons, based on a"Frozen Wave Generator"as the RF converter. This technique represents a major improvement over existing state of the art by eliminating the need for multiple light activated custom solid state switches and the associated laser trigger generator. The key item, an ultra-fast s ...
