— Future generations of air traffic management systems will give appropriately equipped aircraft the freedom to change flight paths in real-time. This will require a conflict avoidance and resolution scheme that is both decentralized and cooperative. Satisficing game theory provides a theoretical framework in which autonomous decision makers may coordinate(More)
The next generation of air traffic control will require automated decision support systems in order to meet safety, reliability, flexibility, and robustness demands in an environment of steadily increasing air traffic density. Automation is most readily implemented in <i>free flight</i>, the segment of flight between airports. In this environment,(More)
The next generation of air traffic control will require automation in order to meet safety, reliability, flexibility, and robustness demands in an environment of steadily increasing air traffic density. Optimization, however, is an inadequate paradigm for the design of a cooperative distributed air traffic control system. The problem stems from a(More)
Wind scatterometry is the determination of vector winds over the earth's oceans using radar data from a satellite scatterometer. In this thesis I develop three techniques which can augment current methods of wind retrieval from scatterometer data. In the first part I investigate methods of obtaining reliable error covariance estimates on retrieved wind.(More)
— Model-predictive control, which is an alternative to conventional optimal control, provides controller solutions to many constrained and nonlinear control problems. However, even when a good model is available, it may be necessary for an expert to specify the relationship between local model predictions and global system performance. We present a(More)
