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 ...

The proposed system is for a lightweight air-deployable expendable system capable of performing functions similar to existing ocean meteorological drifters, with the additional capability of maintaining station and/or repositioning itself on command. The system will keep station better by the sea anchor effect of the inactive tow motor, and has the ability to automatically regain station by towin ...

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 ...

Inexpensive Airborne Expendable Ice Buoys (AXIB) Suitable for Marginal Ice Zone Deployment

A PARTICLE SIZE SENSOR IS REQUIRED FOR ON-LINE PROCESS CON- TROL IN A METAL POWDER FORMING FACILITY. INSTRUMENTS AVAILABLE COMMERCIALLY FOR THIS SENSING RELY ON MEASUREMENTS OF LIGHT SCATTERING AT VERY SMALL ANGULAR INCREMENTS. IT IS PROBABLE THAT THE HIGHLY TURBULENT ENVIRONMENT IN WHICH THE METAL POWDERS ARE FORMED WILL PRODUCE SUFFICIENT ANGULAR DE-VIATION OF THE PROBING LIGHT BEAM TO INVALIDAT ...

MILLITECH PROPOSES TO DESIGN A COMPACT OFFSET CASSEGRAIN ANTENNA SYSTEM TO BE USED AT A WAVELENGTH OF 8 MM FOR CLOUD RESEARCH. THE SYSTEM WILL BE DESIGNED TO GIVE THE LOWSIDELOBE LEVELS CHARACTERISTIC OF AN OFFSET REFLECTOR WHILE GIVING POLARIZATION ISOLATION BETTER THAN 20 DB. THE TRADE-OFF BETWEEN HIGH POLARIZATION ISOLATION AND COMPACT SIZE WILL BE RESOLVED BY USING A GAUSSIAN OPTICS LENS ANTEN ...
