School of Electronic, Electrical and Systems Engineering

Prof. Proudler is recognised both nationally and internationally for his work on adaptive filtering. He is an expert on recursive least squares minimisation algorithms as applied to adaptive filters, and broadband and narrowband ‘phased-array’ beamformers. This includes the fundamental theory as well as numerical stability and real-time implementation issues. He also specialises in the transfer of his adaptive filtering technology to diverse applications areas. Recent successes include feedback cancellation in hearing aids, separation of co-channel communications signals without multiple receivers, and low-cost high-performance magnetic sensor systems.

Prof. Proudler has been the principal researcher on many MoD-funded research projects. Some of these have addressed basic signal processing needs such as numerical stability and efficient computation. Others have focused on the application of adaptive signal processing algorithms to military systems such as a ‘smart’ antenna algorithm for HF communications, signal separation for ESM purposes, magnetic detection for maritime surveillance, and GPS anti-jam systems. He has published some 60 research papers, contributed to three textbooks and holds a patent on an adaptive filtering architecture.

He was awarded the John Benjamin Memorial Prize, in 1992 and 2001, and the IEE J.J. Thomson Medal, in 2002, for his work on signal processing algorithms. He was Visiting Professor at King’s College, London from 2002 to 2005. He was an Honorary Editor for IEE Proceedings: Radar, Sonar and Navigation for ten years. He became a DERA (now QinetiQ) Fellow in November 1998 and a Senior QinetiQ Fellow in 2007. He was a member of the Advisory Board of the Institute of Sound and Vibration, Univ. of Southampton from 2003 to 2011.  He has been on the organising committee of several international conferences. He is now an independent consultant. He is a Fellow of the IET and the IMA.
