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 ...

Giant Grouper (E. lanceolatus) is one of the most desirable marine fish in the world. Its robust nature, tremendous growth rate, superb quality flesh and high value make it ideal for open ocean aquaculture. This species has also been heavily overfished throughout its range. Hatcheries could supplement commercial and recreational fisheries through stock enhancement, and also aid grouper fishery ...

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 ...

Dozens of popular radar systems are installed on all sizes of aircraft, however the fundamental capabilities of these radars can be defined using only a few parameters such as the pulse width, pulse rate and scan rate. Each radar has its unique interface to operator controls and displays but the input controls and outputs are fundamentally the same. This proposed research effort seeks to utilize ...

Ozone is arguably the most important trace gas in the atmosphere, and improved monitoring of ozone throughout the atmosphere is essential. This Phase 2 project continues the development of a complete, automated system for measuring ozone from on board commercial aircraft. There is already one program within NOAA, CAAMP (Commercial Aircraft Atmospheric Measurement Program), for measuring a variety ...

In our Phase 1 work we were able to replicate and build on recent results at NIST with superconducting transition (SCT) thermometers, which suggested that dramatic improvements may be achieved in detectivity and range of application, of cryogenic electrical substitution radiometers. Cryo-ESR's are widely used as the most accurate absolute standards of radiative flux and irradiance. In Phase 2, we ...

Lidar systems offer considerable promise for the acquisition of a variety of atmospheric variables with very high spatial and temporal resolution from airborne platforms. Ground-based lidar systems have been demonstrated that measure aerosols, water vapor, and ozone, and airborne windsensing lidar have been flown on several military aircraft. The growing number of commercial airliners, however, of ...
