WE PROPOSE TO DESIGN A FREQUENCY-AGILE MICROWAVE RADAR SYSTEM TO MEASURE SURFACE CURRENTS IN HARBORS AND ESTUARIES. THE PROPOSED SYSTEM WILL BE CAPABLE OF OBTAININGHIGH RESOLUTION MEASUREMENTS FROM PIERS, BRIDGES AND FIXED NAVIGATION AIDS. IT WILL TRANSMIT MULTIPLE FREQUENCIES SIMILAR TO THE HIGHLY-SUCCESSFUL UMASS STEPPED FREQUENCY DELTA K (SFDK) RADAR, WHICH RECENTLY OBTAINED THE MOST ACCURATE C ...

WE REQUEST FUNDS TO SUPPORT RESEARCH FOR INVESTIGATING POSSIBLE WAYS TO EXTEND RADAR WIND PROFILER TECHNOLOGY TO MEASURE HORIZONTAL AND VERTICAL WINDS OVER THE OCEAN. BENEFITS OF DEVELOPING OCEAN BASED WIND PROFILERS INCLUDE IMPROVED WEATHER FORECASTING, TROPICAL STORM MONITORING, ROUTING OF SHIPS AT SEA TO REDUCE FUEL COST, AND TACTICAL BALLISTIC TRAJECTORY CORRECTION. THIS RESEARCH WILL FOCUS ON ...

WE REQUEST FUNDS TO SUPPORT RESEARCH AIMED AT IMPROVING TECHNIQUES TO PENETRATE SMOKE AND THE ATMOSPHERE USING AND ADVANCED PASSIVE MICROWAVE/MILLIMETER WAVE CONCEPT DEVELOPED BY THE UNIVERSITY OF MASSACHUSETTS. THIS TECHNIQUE, REFERRED TO AS APERTURE SYNTHESIS OR SYNTHETIC APERTURE RADIOMETRY, IS A NEW EARTH REMOTE MEANS TO DEVELOP SPATIAL RESOULTIONS AND WIDE SWATH WITH THINNED ARRAY ANTENNAS. T ...

MICROWAVE REFLECTIONS FROM THE OCEAN ARE HIGHLY SENSITIVE TO THE CAPILLARY WAVE STRUCTURE OF THE SURFACE SO OIL SLICKS TEND TO REFLECT VERY LITTLE MICROWAVE POWER. IMAGING RADARS ARE THEREFORE ABLE TO MAP THE SHAPE AND EXTENT OF NAUTRAL AND MAN-MADE MARINE OIL SLICKS. THE EMISSIVITY OF MICROWAVE SIGNALS, HOWEVER, IS INCREASED BY OIL SURFACTANTS AND OIL SLICK THICKNESS CAN BE MEASURED USING A TWO-F ...

This proposal describes a proposed four-dimensional turbulence profiling radar for shipboard use. This radar, termed the Turbulent Eddy Profiler (TEP), is a unique system that continuolusly monitors the intensity of atmospheric turbulence over approximately three thousand volume cells and updates these measurements several times a minute. Using a technique called digital beamforming the TEP system ...

THE MANNER IN WHICH ATMOSPHERIC ENERGY IS TRANSFERRED TO OCEAN SURFACE CURRENTS IS NOT FULLY UNDERSTOOD. MEASUREMENTS OF SURFACE CURRENTS CANNOT BE OBTAINED FROM IN SITU SENSORS BECAUSE OF SURFACE WAVE MOTIONS. A RADAR REMOTE SENSING TECHNIQUE TAHT CAN BE USED TO MEASURE OCEAN SURFACE CURRENTS AND WHICH CAN BE USED FOR FUTURE SCIENTIFIC INVESTIGATIONS IS BEING EXAMINED. RESEARCHERS ARE PREPARING A ...

In this proposal, Quadrant Engineering seeks SBIR funds to develop a ground-based polarimetric millimeter-wave radar for studying the distribution, dynamics and microphysics of nonprecipitating clouds. The proposed radar will utilize a high duty-cycle kylston amplifier, low-noise amplifiers and a 2 m diameter antenna to achieve greater sensitivity than any existing millimeter-wave cloud radar. Pu ...

A tunable microwave radiometer capable of measuring atmospheric temperature and moisture is proposed. Radiometer operating frequency bands will include the water vapor and oxygen absorption lines. Other design objectives include, light-weight (portable), accurate thermal control of critical system electronics, computer control of operating frequency with an accuracy of 1 MHz, laptop computer dat ...

This project will develop a mobile boundary layer radar wind profiler intended for rapid deployment in regions of severe storm activity. The goal of this research will be investigate the feasibility of developing a low cost, low maintenance, mobile instrument capable of profiling vertical and horizontal wind velocities in the lowest 3 km of the atmosphere. The system's mobility and quick setup t ...

In this proposal, Quadrant Engineering seeks SBIR funds to investigate technologies leading to the development of a compact, low-cost multifunction radar system for use aboard an unmanned aerial vehicle (UAV). If successful, the proposed radar system will provide airborne early warning (AEW), ground mapping and ground motion-detection capabilities. Several novel antenna concepts will be in ...
