Kevin Chetty

Dr. Kevin Chetty is a lecturer in the Department of Security and Crime Science at University College London. He is the Module Convener for the Crime Mapping & Spatial Analysis Courses, and the Deputy Director of the newly formed JDI Centre for Security Technology (www.ucl.ac.uk/cst). Kevin’s research focuses on new passive RF sensor systems that exploit wireless communication networks for uncooperative detection of personnel, vehicle and marine targets. Other research interests include target detection and classification using acoustic micro-Doppler signatures, ultra-wideband and through-the-wall radar, and software defined sensor systems. He has experience consulting for both government and industrial organisations such as the UK Maritime and Coastguard Agency and Guidance Microwave. Kevin is a member of the IEEE and IET, a reviewer for the IET Radar, Sonar and Navigation journal, and author to over twenty conference and journal papers.
