Nap-of-the-earth flight is flight as close to the earth's surface as obstacles, terrain and vegetation will permit, so that maximum advantage of masking from threats is obtained. this effort addresses an automated guidance procedure for noe flight that also accounts for obstacles. such automated… More

This proposal is for the design of an integrated navigation system for a robotic vehicle. included in the proposed effort is the formulation of candidate navigation systems incorporating any one of several "dead reckoning" systems (odometer or inertial instrumentbased) and position fixes derived… More

The use of navigation information from the global positioning system, perhaps in combination with inertial sensors, offers the possibility of very high accuracy navigation solutions. this effort will examine several candidate navigation systems, all involving gps, to determine if such systems could… More

The proposed computer-based system to superimpose the image of threat weapons onto the x-ray projection image of hand baggage is based on (1) modeling of x-ray projection images of selected threat weapons in a variety of rotational positions. (2) computer detection and tracking of real-timemoving… More

This proposal is for the design of an effective navigation law for interdicting evasive targets, principally torpedoes. included in the proposed effort is the assembly of existing government-funded torpedo and target-oriented simulations for the purpose of evaluating the navigational law. a key… More

The fundamental objectives of this proposed effort are to specify a transfer alignment algorithm appropriate for a hypersonic weapon system, and to define a simulation appropriate for evaluation of the proposed algorithm. in achieving these objectives, current transfer alignment approaches must… More

The highly sophisticated performance characteristics of the advanced tactical fighter call for the design and development of pilot aids which will help enhance and stabilize operator performance throughout the mission cycle by improving situational awareness as well as reducing workload. this… More

Reduction of aircraft tracking data for precise trajectory determination requires smooth data. if the true trajectory has abrupt changes in it, conventional polynomial least squares techniques will be inadequate to meet precision requirements. furthermore, many test missions could significantly… More

The problem addressed is the automatic location and classification of randomly dispersed objects to an accuracy of 1 cm on the ground in the area of 100 m to 200 m. to avoid interference with the dispersion of the objects any cameras are to be located outside the area, and any makers placed in the… More

A fully operational ibm pc-at based space system concept generation and analysis workstation will be designed and developed. this workstation will allow the user to view an animation of the positions of the sun, moon, planets, earth satellites and earth coastline boundaries from selected orbits and… More

Recent advances in sonar design have improved bathymetric data capabilities to the point that advanced image process- ing techniques are required to extract all the information available. this project addresses such techniques for sonarand navigation system calibration, both premission and… More

Knowledge-based systems provide the potential to develop new capabilities for avionics software systems. knowledge-based systems can intelligently adapt to their environment, focus resources on interesting events, filter and summarize complex input data, and can be easily and rapidly modified to… More

This project will integrate the operation of threat warning sensors with the subsequent threat management responses that might be employed in low-altitude missions. advances in threat warning sensors and in associated data fusion are occurring in "inews" and related programs. "threat management"… More

Tau corporation proposes a new, novel technique and its associated instrumentation for training operators of airportx-ray security systems. the training provided by this new system will greatly improve security checkpoint efficiency. the instrumentation proposed for the trainer system uses… More

There is a proposal to put gps aboard the space shuttle for purposes of providing autonomous navigation. one of the benefits of autonomous navigation will be the ability to land the shuttle in an emergency at any suitable airstrip. if an emergency landing is required, there will be no assurance that… More

Numerous government and industry research and development projects are exploring the application of neural networks within embedded software systems. although models, implementations, and applications of neural net technology are multiplying, little attention has been paid to testing, benchmarking,… More

Much research and development is underway to construct intelligent training systems capable of adapting themselves automatically to an individual student's performance and learning modalities, and to determine the feasibility of applying of neural network technology to the development of these… More

Flight simulators of the future will employ photo-based image generators to create realistic full-photographic simulated images in real time. pilots in training and also those rehearsing specific missions will not be flying through the cartoon-like reality of past simulators but through a… More

The proposed effort develops a system using a video image processing to measure the focus, or defocus, of an optical instrument over a selectable area of the image, and then to adjust the focus. the technique can be applied to objects that are silhouettes or to objects or regions that have only… More

Recent developments in the field of artificial neural networks have demonstrated the utility of these systems for a variety of purposes including pattern recognition, associative memory, and control. to date, the majority of these applications have been implemented of conventional sequential… More

The focus of this project will be to define an innovative approach for associating target reports from dissimilar sensors including forward looking infrared (flir), tv and millimeter wave (mmw) radar. this approach includes corrections for sensor misalignments, filtering of sensor measurements for… More

In the past, sensor management systems have been constructed utilizing a variety of ad hoc methods and heuristic "rules of thumb." little or no attempt was made to provide a consistent intellectual framework or system level architecture for supporting sensor management functions. this approach made… More

We propose to design, evaluate and develop a pc-windows based workstation for automated video data reduction specially addressing the vehicle track and lateral placement mesurement for human factor and highway safety experiments. this design leverages a multiple person-year investment at tau in the… More
