We propose to develop the signal processing algorithms to detect and maintain continuous track of ground vehicles with an airborne surveillance radar. Three modes of radar operation are needed to detect and track all targets of interest: a conventional SAR mode for stationary vehicles, a modified SAR mode for slow moving vehicles, and an MTI mode for fast moving vehicles. All modes will be base ...

Carbon-Carbon components, initially developed for the aerospace industry, have experienced minimal commercialization over the past decade due to cost constraints. C-C composites are excellent candidates for a wide variety of components such as automotive clutches, brakes, and liners, due to its friction and heat transfer characteristics. Recently, within the past five (5) years, new C-C processing ...

This proposal develops design details and materials concepts for a Collapsible Rigid Inflatable Boat (C-RIB). The proposal seeks to develop a seaworthy prototype within Phase I budgets and time- frames. A multi-disciplined team approach will develop a lightweight, armored, low observable craft launchable from submarines, aircraft, and surface vessels. Commercial versions are contemplated in collap ...

The GAO has reported to Congress that the loss due to fraudulent health care activity amounted to an estimated $84 billion in 1992. The ability to detect fraud and abuse is critical to the reduction of health care costs. The claims processing system will soon undergo rapid change with the introduction of rapid payment transaction processing systems. The emphasis on rapid turn around combined with ...

The use of CFD in the design and analysis of flight vehicles requires specialized knowledge about factors such as algorithm options, gridding methods, physical models, and runtime performance. This knowledge is needed to properly set up a calculation and to monitor the solution during execution of the code. The objective of this work is to create an intelligent software environment t ...

The proposed work will decrease the computer CPU time required for computational fluid dynamics (CFD) caluations by two orders of magnitude relative to CFD methods currently used for design. This will be done through the use of high-accuracy spatial discretization schemes and high-over outer boundary conditions t decrease grid sizes, and by the development of improved convergence algorithms compa ...

A methodology for assessing the visual quality of digitized imagery and video will be developed. Loss of image quality is noticed after an image has been compressed and reconstructed using JPEG, wavelet or fractal compression techniques. Test by IAs and formal subjective tests (e.g., CCIR 500) can provide reliable, relative measures of video quality. However, such testing is time-consuming and ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...
