Research interests
My research interests are mainly in the area of radio science applied to radio propagation and remote sensing:
- Atmospheric radar (weather radars) and radiometer technology
- Active and passive remote sensing techniques (e.g., signals of opportunity for atmospheric science)
- Radio propagation modelling and prediction 1–100 GHz (e.g., parabolic equation modelling, rain scattering, scattering from vegetation, indoor/urban ray-tracing)
- Passive radar (in collaboration with University of Adelaide)
- Bistatic and multistatic netted radar, especially at millimetre-wave frequencies
- CIRCE mission: L1/L2/L5 GPS receiver science payload, TOPCAT II
- ORPHEUS mission: L1/L2/L5 GPS receiver science payload, TOPCAT IIb
- Global Navigation Satellite System technology (e.g., GAARDIAN, SENTINEL, AJR, tropospheric delay modelling, GNSS jamming and jammer location hardware development)
- Compact Rb & Cs vapour atomic clocks: low-noise, high-precision analogue design and RF synthesizer design
- RF engineering: low phase-noise frequency synthesizer design, software-defined radio (SDR), antenna design
- ESA Phase 0 study: ROARS, GNSS science receiver
- GXTT: Global Xpress Time Transfer - Precision Time Transfer from GEO, ESA NAVISP-EL2-209 study with Viasat/Inmarsat
- UPDATE Phase 2, UK National PNT Digital Twin, ESA NAVISP-EL3-035 study with GMV
Research collaborators include: Chronos Technology, Defence Science & Technology Laboratory, Raytheon UK, Met Office, Navtech Radar, CPI TMD Technologies, Biral/Senseca, Viasat/Inmarsat, Starion UK.
Teaching activities
I've taught almost everything and anything over the last 30 years, but my current teaching activities are:
