The Sensors Systems and Circuits group undertakes research into new systems and techniques, carrying on the tradition of innovation and excellence set by Professor Harold Barlow, Professor Alex Cullen and Professor DEN Davies. New technologies are currently presenting new opportunities for sensors, which are allowing radical changes in the way that such systems can be exploited. UCL research is pioneering work into novel systems and applications.

Particular themes of our work are:

  • Radar systems and signal processing, including bistatic and netted radar, multifunction phased array radar, waveform design, synthetic aperture radar, non-co-operative target recognition
  • Sonar signal processing and synthetic aperture sonar
  • Electromagetics
  • Advanced frequency synthesis techniques
  • RF-ID tags and associated location systems
  • Antenna arrays and antenna measurements
  • Terahertz systems for sensing and imaging
  • Optical probing techniques

Much of the work is collaborative, with partners in industry (Thales, BAE Systems, AMS, …) in academia (Cranfield University, University of Pisa, Birmingham University, …) and is funded by a range of organisations including EPSRC,  NERC, EU Framework programmes, UK MoD, via Defence Technology Centres and Towers  of Excellence and the US Air Force.

Acquisition of a new anechoic chamber facility, funded by SRIF II, will allow exciting new experimental work in these areas.

We are currently exploring a specific collaboration with the Communications and Signal Processing Group at Imperial College, on Intelligent Signal Processing, and including the application of array signal processing techniques to a variety of radar, sonar and EW problems.
