ABSTRACT:A program to develop a compact, HOT-FPA-based MWIR imager for small UAS sensor and strap-down seeker applications is proposed. The proposed system builds upon Surface Optics real-time broad-band and spectral imaging activities to generate a compact sensor appropriate for both ground and airborne operations that includes real-time detection and tracking of targets. Integrated into the proc ...

ABSTRACT: Space Situational Awareness is concerned with the physical characteristics, capabilities, operations, health, and potential threats posed by space objects. This information is gathered largely via radar and optical data collection facilities. Due to the increasingly large number of space objects and relatively limited number of collection facilities, it's important that collection operat ...

ABSTRACT: In Phase I, CFDRC in partnership with ESI, have developed and validated a physics-based CFD tool to quantify fuel spurt caused by impact and penetration of fuel tanks. CFD tool development, qualification and validation study showed good correlations with experiments in terms of fundamental physics including: a) droplet formation, breakup, size, timing and distribution; b) cavitation zone ...

We will evaluate a novel warming method, developed by our collaborator John Bischof, that promises solution of one of the remaining barriers for banking of large organs and vascularized composite tissues. The method involves radiofrequency and magnetic nanoparticles to obtain rapid uniform electromagnetic rewarming of biological materials instead of warming from the outer boundary using convection ...

The long term goal of the proposed research is to develop improved methods for cryopreservation of complex tissues at extreme low temperature. An innovative approach is taken in the proposed line of research, where synthetic ice modulators (SIMs) are combined with established cryoprotective agent (CPA) cocktails to create more favorable conditions for cryopreservation in a process known as vitrifi ...

ABSTRACT:A new algorithm, the Daylight Object Restoration Algorithm (DORA), has been developed. DORA includes a novel implementation of the multi-frame blind deconvolution image restoration concept which recovers high-quality object estimates from sequences of degraded images. DORA removes the effects of atmospheric aberration in images recorded at ground-based telescopes, and is designed to opera ...

ABSTRACT:The objective of the project is to develop models for secondary debris generated by mobile targets. This includes the vehicle component breakup due to expanding high explosives and primary fragments as well as the associated airblast that propagates into the environment propelling secondary fragments from the vehicle. The overall scope of the project involves developing the computational ...

ABSTRACT: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: FIRST RF has teamed with University Research Foundation (URF) and Radiometrics Corporation to develop a passive radiometer-based geolocation system for use with a wide variety of USAF platforms. The system will be comprised of a ruggedized, near-COTS radiometer system by Radiometrics Corporation, augmented with a robust 2-D scanning beamsteering antenna by FIRST RF Corporation and enhanc ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...
