Herein, an innovative aircraft weighing system based on a set of piezopolymar film pad sensors is described. The wieghing system, which would operate automatically as the aircraft taxi over it, would be unobtrusive, accurate, and reliable. These sensor pads could be integrated into the flight deck surface below the grated rubber surface finish. These thin (20-30 mils) piezopolymer sensing pads ...

INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCIATED METHODOLOGY FOR PERFORMING RAPID AND ACCURATE MEASUREMENTS OF RANGE/LOCATION OF OTH THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITYWITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/ PROCESSING EQU ...

1Innovative techniques for radar high angle resolution are proposed for investigation in a Phase I effort to enable the resolution of the direction of arrival (DOA) of returns from multiple targets that fall within one beamwidth and within the same range and Doppler Cells. The techniques proposed emphasize the pursuit for optimal utilization of available aperture space, by a combination of arrange ...

Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

Marine storms strongly affect operations at sea, both DoD and commercial. The DMSP SSM/I clearly depicts certain features of marine storms. Improved depiction of these storms will aid nowcasting in support of execution.of operations at sea and fore- casting of the evolution of these storms in support of planning. However, SSM/I data as well as many other satellite data have only small impacts on t ...

change induced in the wavelength of ruby R-line fluorescence. Timehe resolution will be 0.1 microsecond. Axi innovative detector of this wavelength shift avoids the need for a dispersive optical system and streak camera, as previously used. The fluorescence will be excited by an argon ion laser. materials having less temperature sensitivity than ruby, and the use of non-laser excitation sources.

This exploratory development proposal addresses a class of novel algorithms specifically designed for tracking and engaging maneuvering air, naval or ground targets. The key technical innovation is the development of linear and nonlinear target tracking algorithms using the recent results in H(Infinity) estimation methodology to modify the classical Kalman filter and extended Kalman filter algorit ...

The introduction of a whole new class of transform methods, notably the wavelet transforms, which permit decomposition of observed phenomena into different physical scales and the computational leverage provided by multiscale image processing tech- niques, when applied to multisensor Lmage data, promises to increase the sensitivity and reliability of Lmage processing systems in several application ...

ALPHATECH has recently developed an integrated software environment for developing and testing prototype fault detection and identification (FDI) systems. It has been applied with excellent results (zero false and missed alarms, with 4% probability of deferral to the next decision time) to helicopter gearbox test-stand accelerometer data. The front-end of our environment extracts novel feature set ...
