The Lincoln Beaver Works Signal Processing Center is a research and teaching center dedicated to the development and demonstration of novel algorithms and techniques for processing signals, images, and data for a broad range of sensor system applications, including space-borne and airborne radar, passive sonar, advanced wireless communications, signals intelligence, and robust navigation.  The Signal Processing Center will encourage cross-fertilization with other centers within Beaver Works to ensure relevance in the signal processing applications which are pursued. Current areas of investigation include adaptive sensor array processing, signal detection and estimation, pattern recognition, multichannel communications, underwater acoustics, and systems analysis.
