JRM proposes a novel context-dependent, signature-based approach to improve the automation and quality of material-classification of imagery and arbitrary n-channel remote-sensed data. In the Phase I, JRM will design three key components: (1) anautomated N-channel signature-predictive material classification algorithm, (2) a pixel-material spatial-correlation refinement algorithm and (3) an iter ...

This Phase I SBIR Project will develop an Advanced Unbalance Control (AUC) system based on active magnetic bearing (AMB) technology and advanced feedforward control algorithms. The AUC system will offer at least an order of magnitude increase in bothresponse speed and unbalance response reduction as compared to the best available mechanical unbalance cancellation methods. This will be accomplish ...

Drag reduction for aerial vehicles has a range of positive ramifications: reduced fuel consumption with the associated economic and environmental consequences, larger flight range and endurance and higher achievable flight speeds. Recent numerical results yielded solid evidence that very small disturbances in the form of a spanwise traveling force wave on a surface could reduce drag by 70%. Our pa ...

By re-examining the basic physics of underwater signal propagation in the context of recently developed notions of state-space methods for dynamical systems, we have formulated a new active sonar signal-processing model. This model is based on morerealistic assumptions about the possible return waveforms, nongaussian noise, clutter and reverberation than existing approaches. Implementing a bank of ...

The objective of the Advanced Anti-jam Design Techniques effort is to make a controlled Radiation Pattern Antenna (CRPA) have more elements without increasing the size, or make it the same antenna (i.e., same number of elements) smaller. The moreradiating elements that are available in a CRPA design, the more response nulls can be directed towards jammers. The inherent design problem that needs ...

Adaptive Digital Array Radars (DARs) promise significant sensor performance breakthroughs when antenna arrays become sufficiently large to achieve useful gain and directivity. Recent electronics technology advancements have progressed to the point thatadaptive DAR sensors will soon support operational requirements for many important US Navy applications.A Reconfigurable DAR Processor (RDP) address ...
