Dr David Andrews

Academic and professional qualifications

I am currently a Senior Research Fellow developing novel microwave and millimetre wave based systems for the remote detection of weapons and other security applications.

Previously, I had over twenty years experience in the Department of Physics & Astronomy in the University of Manchester in developing spectroscopic and laser based systems for applications for the aerospace, medical and nuclear industries.

Research expertise

Development of systems to remotely detect concealed weapons, explosives or contraband using high frequency (MHz to THz) electromagnetic waves Real time data acquisition, signal processing and signature extraction for imaging and non-imaging systems
