This Phase II effort will further develop a technique to improve current seeker discrimination and tracking capabilities using a unique particle filter algorithm (PFA) approach. The advancement represents a significant upgrade to current and future seekers facing advanced threats in stressing environments. Quantifiable improvements over many facets of the current approach have been realized during ...

The Oceanit¡¦s/APL Foveal InfraRed Search and Track (FIRST) prototype is a dual channel cryogenic WFOV optical sensor system. FIRST provides multifaceted support for an airborne IR search and track and uses the unique Multi-target-tracking Optical Sensor-array Technology (MOST) sensor chip, which has been developed at MDA. FIRST supports instantaneous field-of-view up to 90 degrees, with 360 deg ...

The objective of this proposal is to develop advanced radiation transport modeling techniques that accurately and efficiently treat transport in media having widely varying optical properties; in particular, hot gases and plasmas with optical depths ranging from the optically thin to the optically thick regimes. We will develop a hybrid diffusion-Monte Carlo (HDMC) model that efficiently transpor ...

A new material and processing technology has been developed and demonstrated that will dramatically reduce the cost of manufacturing and refurbishing large aluminum based mirrors for optical test applications. Such precision mirrors are also required for surveillance, directed energy, cryo-vacuum scene generation, optical testing, and DoD-sponsored space programs. Traditional aluminum mirror techn ...

Gel propulsion systems combine the best characteristics of solid and liquid propellants. The gel system stores like solid propellant, but flows like a liquid when pressurized, enabling throttle and restart capability similar to liquid propellants. An ena

Recent statistics from Operation Iraqi Freedom (OIF) show that significant proportion of soldiers injured in blast explosion endure traumatic brain injury (TBI). At the same time our understanding of TBI mechanisms and protection against kinetic and blast

The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Hypervelocity flows are characterized by high temperatures, real gas effects, nonequilibrium chemistry, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with automatic domain decomposition for a wide range of Air Force applic ...

Nanoscale infrared detectors are emerging as a potentially powerful alternative to traditional infrared detector technologies. The University of New Mexico has developed dots in a double well (DDWELL) quantum dot infrared photodetectors which have a spectral responsivity that can be tuned by controlling the bias voltage applied. In this Phase II effort, Polaris Sensor and UNM would fabricate a g ...
