Prof Paul Cannon is both a physicist and an electronic engineer who works at the interface of the two disciplines. He is an academic at the University of Birmingham with considerable experience of working in government research laboratories and in industry.

Paul has held many leadership roles in addition to his research into the physics of the ionosphere, its effects on radio systems and space weather. Paul has served as QinetiQ Senior Fellow, Chief Scientist (Communications Division) and as the University Partnerships Director. He was Director of the Poynting Institute at University of Birmingham, Editor-in-Chief of the journal, Radio Science and is President of the International Union of Radio Science (URSI). Paul has served on Government committees and provides consultancy to a number of organisations.

He was elected a Fellow of the Royal Academy of Engineering in 2003 and appointed to the Order of the British Empire (OBE) in 2014.

Paul has worked at the intersection of research and industry for more than 30 years and in his role as the Director of the Poynting Institute at the University of Birmingham he led a partnership between industry and academia dealing with autonomy (air, land and space vehicles) and space science and engineering.

Paul is a leading figure in radio science and systems, being interested in a wide range of radio propagation, radio environment and space science problems and how they impact communications, radar and navigation systems. He has made numerous personal and team leadership contributions to mitigating the impact of the environment on radio systems.

Paul initiated the UK Ministry of Defence (MOD) ionospheric space weather programme in 1986 and he led and nurtured it for over 25 years. This he did both as a civil servant within the MOD and, on behalf of the Ministry whilst working both in QinetiQ and later also at the University of Birmingham. During this period he moved military space weather R&D from a Cinderella topic to a core technology with an articulated military requirement. Much of this was, and continues to be, achieved with the benefit of bilateral and multi-lateral arrangements which he facilitated with the US DoD and other nations providing substantial benefit to the UK.

Paul has published many scientific papers including those addressing ionospheric modification, meteor scatter communications, HF communications and radars, space radars and ionosondes. In addition, he is the author of many classified reports and a number of book chapters. Paul initiated and led the Canadian-Norwegian-Swedish-UK team (DAMSON) which defined the requirements for the robust military HF modem, STANAG 4415, now used throughout NATO. In recent years the team have developed and transitioned a new generation of real-time (assimilative) ionospheric models from laboratory to the user. He and his team conducted seminal measurements and have built models to describe the impact of the ionosphere on space radars. The team have also been involved in ionospheric modification rocket experiments being part of a UK-US collaboration which he initiated.

Paul has served on the UK Cabinet Office, Space Weather Project Board, has been an expert witness to the House of Commons Science and Technology Select Committee and has supported the Prime Minister’s Committee on Science and Technology.

Applications are always welcome.

After early research at Southampton University and in the satellite communications industry Paul was appointed to the Ministry of Defence (MOD) Royal Aircraft Establishment (Laboratory) where he was rapidly promoted and offered a “fast track” career in London.  He  declined this opportunity preferring a scientific career.

His early work on meteor burst communications (MBC) was significant in that he was the first to identify a signal loss mechanism due to signal polarisation rotation by the ionosphere, in the upper atmosphere. This, and subsequent work on the use of phased arrays, facilitated MBC systems operating with significantly enhanced data rates. These early successes convinced him that important radio engineering advances could be made via a detailed understanding of both the radio propagation and the atmospheric environment through which those signals propagate. Around this time (1989) he was invited to work on sabbatical at the University of Massachusetts.

Subsequent R&D resulted in the development of new and novel instrumentation to measure the ionosphere, new fast analytic ray tracing techniques and non-linear dynamical modelling to forecast the ionosphere. These many initiatives have provided innovative solutions to problems in high frequency (HF) systems. Of particular note was the pioneering work and his leadership (technical and managerial) of the international DAMSON programme (1993-2000) to measure and understand the HF communications propagation channel. This work, carried out by a team of ~10 persons in Sweden, Norway, Canada and the UK was carried out in cooperation with the major communications modem manufacturers. NATO’s robust HF modems are based on the results of this work.

Until 2013 he led the QinetiQ team delivering new techniques to support the design of innovative new sensors based around space radars, over-the-horizon-radar and other surveillance systems. This included formal assimilation of measured data into models and ionospheric scintillation measurements and modelling using phase screen approaches. During this time he was the first to measure the trans-ionospheric impulse response which he did using a major radar facility located in the Marshall Islands. This period has included investigations of the practical effects of climate change on the ionosphere.

Current personal research is addressing the effects of the ionosphere on space based radars and mitigation strategies (Birmingham University).

Leadership

• In order to facilitate his research Paul initiated the RF Operating Environments (RFOE) Group at QinetiQ. During his leadership RFOE rose to be one of the largest research groups of its kind in the UK. The Centre had a wide remit covering (primarily) communications systems operating from 10 kHz to 60 GHz.
• In 1998 Paul was appointed to a part-time chair (one day per week) at the University of Bath where he integrated QinetiQ and University aspirations to mutual benefit in a Partnership through the building of a small team consisting of research assistants and students.
• From 2000-2008, Paul served as Technical Director and then as Chief Scientist of Communications Dept at QinetiQ. In this role he reported to the Director of Communications Division with ~400 staff. He was responsible for innovation and for horizon scanning. In analysing the resources allocated to these various research programmes, he assessed both the short -term value (business or in society) and the value of discovery which will provide innovation options in the future. In this role, he successfully initiated a multi-million pound Galileo satellite business.
• From 2004-2005 Paul served as co-Director of the pan-QinetiQ University Partnership Scheme reporting to the Technical Director of QinetiQ. He developed new ways for QinetiQ to Partner with a small number of Universities to mutual benefit.
• In late 2009 Paul conceived and commenced negotiations to set up the Birmingham Poynting Institute. The Institute was inaugurated in January 2011, with Paul as its first Director on secondment from QinetiQ. 

Summary of Roles on National and International Committees

Paul has participated in, and led the R&D community, in various ways. He has served as Chair of UK Research Council committees, has been a member of the Institute of Engineering Technology (IET) Council and has been vice-chair of the NATO Advisory Group on Aerospace Research and Development (AGARD) Sensors and Propagation Panel.

From 2005-2008 he was Chair of Commission G (the Ionosphere and Ionospheric Radio Propagation) of the International Union of Radio Science (URSI) and from 2011-2014 an URSI Vice-President. He is currently President of the International Union of Radio Science, (URSI).

In 2013 he led the Royal Academy of Engineering Study on “Extreme Space Weather: impacts on engineered systems and infrastructure (pdf)”.

In 2014 he was appointed to the Defence Scientific Advisory Council.
