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 ...

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 ...

We propose to develop ne%v methodolooy allowing non-technical planners to specify, generate, and solve multidimensional logistics network problems. Our approach is based on in- tegrating new generations of multidimensional spreadsheet software, mathematical programming languages, and ultimately interactive map-based user interfaces. Multidimensional logistics network problems include multicommodit ...

The project objective are to develop a new software method for the dynamic analysis of aircraft and to prove the potential of unique high angle of attack Leading Edge Vortex Control (LEVC) devices. The software method will be an upgrade of a current computer code. The upgrade will include the effects of hysteresis during dynamic stall. New methods recently published employing state-spac ...

The opportunity exists to apply evolving technology for nonlinear adaptive control to autopilot design for precision guided munitions. The approach employs artificial neural networks to represent errors made in inverting the nonlinearities in a feedback inverting controller. Using an on-line method for weight adaptation results in a highly effective local approximator to the inversion error. Re ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

The objective of this project is to design a fractual object based image database system which enables video insertion into real time simulation systems. A cost/benefit analysis of the design will be performed to determine the utility of implementing the design in Phase II. Requirements for the Fractal Object Database System will be determined in consultation with the Sponsor and from interactio ...
