Recent research has shown that effective jammer and clutter suppression is best performed with fully space-time adaptive processing. However, allowing adaptive weights on every tap on every element is computationally prohibitive and requires too many samples to converge. Eigenvalue analysis shows that the required number of degrees of freedom (DOF) is significantly less than the dimensionality of ...

THIS PROPOSAL DESCRIBES THE EVALUATION OF REQUIREMENTS FOR REMOTE WEATHER SAMPLING SYSTEMS APPLIED TO A SPECIFIED UNMANNED METEOROLOCIALRECONNAISSANCE AIRCRAFT. DATA TO BE GATHERED INCLUDE CLOUD STATISTICS, WATER CONTENT AND PARTICLE SIZE, DENSITY AND WIND. LIQUID WATER CONTENT MEASUREMENT IS CONSIDERED BASED ON USING EXISTING INSTRUMENTS AND THE PROPOSER'S CONCEPTUAL DESIGN OF A NEW INSTRUMENT. D ...

THE LIQUID WATER CONTENT OF CLOUDS IS ONE OF THE MOST FUNDAMENTAL QUANTITIES IN THE ATMOSPHERE. YET, NO INSTRUMENT HAS BEEN DEVELOPED FOR MEASURING LIQUID WATER CONTENT IN BOTH LIQUID AND SOLID PHASE CLOUDS. THIS IS A PROPOSAL TO DEVELOP THE PRELIMINARY DESIGN OF AN AIRBORNE INSTRUMENT FOR MEASURING LIQUID WATER IN ALL NATURAL CLOUDS, WITH EITHER LIQUID OR ICE CLOUD PARTICLES. THE SYSTEM WILL FEAT ...

The 3DIC concept is based on using multiple levels of thin film dielectric material, each having its own ground plane and microwave circuits, to stack up multiple circuit functions on top of each other. This approach reduces the IC footprint thereby reducing the usage of the semiconductor real estate, leading to substantial reduction in cost as well as improvement in performance. The phase 1 tec ...

An electronically scanned conformal array is proposed for a new generation of air-to-air missile seeker antenna. This new type of antenna array has the potential to impact the capabilities and performance of new missiles in multiple areas. - Cost Reduction - The seeker antenna system proposed is predicted to be considerably simpler to manufacture thereby reducing the cost. - This conformal array a ...

This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative human-computer controversy over how to implement such capabilities, including how to ascertain the ...

Recent trends in the closure of military installations, requirements for the demilitarization and disposal of energetic materials and munitions, and environmental remediation obligations have produced a corresponding requirement for efficient processes which can detect the presence of energetic or explosive materials, extract them from the surrounding soil, air, or water, and modify or convert the ...

Atlantic Aerospace offers to define, develop and analyze a new spread spectrum code acquisition technique having breakthrough potential for decreasing the product of acquisition time and acquisition processor speed for acquisition of GPS signals relative to currently employed techniques. The basis for this claim already exists in results of the company's contract an dcorporately-funded research.I ...

The use of advanced composite materials in all applications has increased dramatically, but the methods for managing and processing have remained unchanged for thirty years. Advanced, mulitple sensor technology has been demonstrated to reduce process time and costs. AvPro proposes to develop a single sensor system to provide multiple data inputs. It would be a means to validate models for proce ...
