The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing "typical day" meteorological data couples innovative search techniques applied to long-range historical arch ...

This proposal provides a breakthrough solution to realize a compact broadly-tunable THz local-oscillator, whose tuning range covers 0.8-1.2 THz with flat output power in excess of 200 uW. The innovation is based on high efficiency intra-cavity difference frequency generation. A dual cavity laser is designed to generate two separate frequency lasers, which share an EO crystal inside the cavity for ...

Agiltron has developed a breakthrough modular IR imaging technology that employs a photomechanical effect, in which an array of micro-machined sensor pixels converts IR radiation into visible light signals that can be optically detected by commercial off-the-shelf CMOS or CCD visible-light imagers. With commercial CMOS imagers achieving multi-megapixel resolution, the resolution of the modular Agi ...

Active interrogation holds the most promise for detecting heavily shielded materials at a distance. This effort will use pulsed neutron excitation of fission reactions in the target being inspected in conjunction with an imaging detector. Special nuclear material (SNM) that is present will undergo fission reactions that generate prompt and delayed neutrons which will be emitted by the target. Th ...

The proliferation of weapons of mass destruction such as nuclear missiles and “dirty bombs” are a serious threat in the world today and especially to the well-being of the United States. Preventing the spread of these nuclear weapons has reached a state of heightened urgency in recent years, more so since the events on September 11, 2001 and its aftermath. The presence of nuclear weapons can ...

High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD applications) and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Unfortun ...

Recent advances in scintillator materials research have resulted in the development of lanthanum halides detectors. These detectors offer improved energy resolution, faster emission and excellent temperature dependency and linearity characteristics. However, the lanthanum halides crystals have not yet been grown to preferred large sizes. Moreover, this material possesses a fatal drawback of being ...

Infrared (IR) detection is an integral part of the Global War on terrorism. Vandium Oxide based micro-bolometers are the current state of the art in uncooled IRFPA. The need for higher resolution 1280X960 arrays that operate at low power for man-portable applications include 24 hour surveillance and targeting . Carbon Nanotube (CNT) based IR detectors could fill this need. CNTs have unique electri ...

This Phase I SBIR project describes our plan to develop a compact scanning polarimetric cloud radar for observations of sea spray from a variety of airborne platforms. Our effort will focus on the design of a compact, lightweight W-band polarimetric scanning radar system that will be suitable to operate onboard the NOAA P3 or NOAA/NASA Altair UAV aircraft. Phase I design activities will include ...

This proposal describes the development of low-cost, microwave integrated circuit receivers for a synthetic aperture Hurricane Imaging Radiometer (HIRad). The HIRad system, designed to generate high resolution ocean surface wind speed data in a push-broom imaging mode, will provide a variety of benefits, including improved hurricane model initialization and detection of fine-scale storm structure ...
