Sensing & Signals

The sensing and signals group focuses on fundamental theoretical and methodological aspects of information processing with a wide variety of important and exciting applications. Recording and analyzing signals, images, and electromagnetic waves is a key component of Duke's interdisciplinary research in ECE. The researchers in this area tackle challenging problems ranging from the measurement of lightening to improving hearing with cochlear implants and from homeland security to the next generation of digital cameras.

Research in this area focuses on the following themes:
  • Statistical signal processing for remote sensing
  • Surveillance radars and microwave remote sensing
  • Active and passive sonar
  • Ocean acoustics and medical imaging
  • Auditory prostheses and pattern recognition
  • Sensor networking
