radar at st Andrews

The Group has investigated mm-wave radar techniques over several years, originally with an emphasis on the use of quasi-optical techniques to realise low-loss, fully polarimetric systems.  We also made a brief study of correlation-based noise radar which would be suitable for low probability of intercept (LPI) applications.

In recent years, the main radar research activity has been based around remote sensing applications of mm-wave radar.  In particular, the AVTIS system (All-weather Volcano Topography Imaging Sensor) uses a ground-based, portable 94GHz FMCW radar to image the topography of volcanic lava domes.

Research interests include:-

  • Radar imaging
  • Long range, high resolution FMCW radar
  • FMCW transmitter linearisation
  • FMCW transmit-receive leakage suppression
  • Nanosecond pulsed radar
