About

In October 1986, following 3 years’ postgraduate research at the University of Wales Institute of Science and Technology (UWIST) in the application of hybrid microwave integrated circuit fabrication techniques to the production of millimetre-wave oscillators, I joined the Rutherford Appleton Laboratory (RAL) of the Science and Engineering Research Council (SERC).

Between 1986 and 1989, I worked in RAL’s Tropospheric Propagation Group on the design, construction and operation of both ground-based and airborne measurement systems for the characterization of microwave radio propagation effects. This work formed a major UK contribution to the international COST-210 project of the European Union.

Since 1989, I have been responsible for engineering management of the experimental programme of the Radar Group within RAL’s Radio Communications Research Unit (RCRU). This has involved the design, construction, testing, installation, operation and documentation of advanced polarimetric, Doppler, bistatic, coherent, pulse-compression and millimetre-wave radars, used for both radiowave propagation and meteorological research in the UK and overseas.

These projects have been supported by the UK Radiocommunications Agency, Ofcom, the Meteorological Office, ESA-ESTEC, the European Union, the Natural Environment Research Council, the Japanese National Space Development Agency and Communications Research Laboratory, MoD, DERA, DSTL, SSTL and various University research groups. The approximate total hardware value of the equipment that I have personally developed is £4.5 M. In addition, I have been responsible for staff-effort commitment and group infrastructure purchases amounting to a further £6.5 M.

As a result of my promotion from Senior to Principal Engineer in October 1998, I became RCRU’s Head of Engineering Group. The Engineering Group’s mission is the development of RF, microwave and millimetre-wave instruments for the entire experimental programme of RCRU. Recent projects for which I have had management responsibility include millimetre-wave radiometers, satellite beacon receivers, terrestrial communications links and several new meteorological radar systems.

In addition to technical matters, my work involves the preparation of bids and proposals, responsibility for financial and personnel issues, and liaison with customers. I also play a wider role in the management of RCRU as a whole, with a special responsibility for maintaining state-of-the-art technical facilities and for the promotion of a professional development culture amongst its engineering staff.

In December 2004, along with 2 members of my group, I was awarded the Sir Charles Wheatstone Measurement Prize of the Institution of Electrical Engineers for “outstanding work on ‘Radar measurements of cloud, precipitation and related atmospheric processes’ ”.

Since 2005, I have played a key technical and management role in the In-Orbit Testing (IOT) of Europe’s first ‘Galileo’ navigation satellites, Giove-A and Giove-B. This work earned my team and I a personal congratulation from the Director General of the European Space Agency (ESA); recognition by ESA’s Galileo Project Manager for our contribution to Giove-A’s ‘Full Mission Success’; and the award of the ‘Diploma of Giove-B’, reflecting ESA’s acknowledgement of the Chilbolton Observatory as a ‘centre of excellence for in-orbit testing work’ relating to Global Navigation Satellite Systems (GNSS).

In July 2006, as a consequence of my successful leadership of RAL’s work on the Galileo satellite programme, I assumed additional responsibilities, as Head of Space and Special Projects, for the management of all space-related and special projects at the Chilbolton Observatory.

Between 2008 and 2011, I was involved in consultancy work for the Met Office (UK weather radar network renewal programme); NERC (MST Radar Facility upgrade programme); DSTL (Chinese navigation satellite characterisation, space surveillance radar); and for the British National Space Centre / UK Space Agency (on ESA’s Space Situational Awareness (SSA) Preparatory Programme).

Since 2010, I have been an external member of the University of South Wales’ (USW) Mobile and Satellite Communications Research Group (MSCRG) within the Faculty of Computing, Engineering and Science. This has facilitated a joint USW-STFC collaborative research programme in advanced satellite communications systems, involving me in MSc and PhD research student supervision and mentoring, and resulting in numerous publications and presentations at national / international conferences and in leading journals.

In September 2011, I was appointed Head of Chilbolton Group in RAL’s Space Science and Technology Department (now known as ‘RAL Space’), managing a team of 10 engineers, scientists and technicians. My responsibilities included the delivery of STFC-NERC Service Level Agreements covering the Chilbolton Facility for Atmospheric and Radio Research (CFARR) and the Mesosphere-Stratosphere-Troposphere Radar Facility (MSTRF), in addition to various contract-funded projects involving ground-station, LOFAR, GNSS, and SSA-related work.

Between 2011 and 2014, my work focussed on a succession of contract studies for DSTL involving use of the Chilbolton radar for space surveillance / satellite tracking and for space object characterisation. I was also active in the area of SSA policy formulation, providing technical assessments, advice and radar measurement data to various national and international organisations. Other work during this period involved VHF / UHF ground-station development for the UK’s first cube-sat mission, UKube-1, and commissioning of a 6.1 m diameter ground-station antenna at Chilbolton to support government and commercial S- and X-band satellite missions. From 2013 to 2014, I represented STFC and the UK radio astronomy community on the government’s top-level radio spectrum policy committee.

My current research interests include the development of advanced coherent radar techniques and signal processing for radar meteorology and atmospheric sounding measurements; the detection and characterization of space-objects using polarimetric and high range-resolution radars; aerospace and military radar applications; in-orbit testing of satellite payloads; ground-based, airborne and space-borne remote-sensing, surveillance, reconnaissance and signals-intelligence systems; and technologies for future high-capacity satellite communications systems.
