Welcome to the UCL Radar Research Group Wiki Page
The aim of this wiki is to share information on the research that is being carried out in the group both internally and externally.
Thanks for dropping by.
There is a radar phenomena coined “Ring Angels” by Eric Eastwood which describes the effect of early morning. His original paper on the matter can be found here :https://royalsocietypublishing.org/doi/pdf/10.1098/rspb.1962.0042
Below is a link to a slide which has an image of the effect: ring_angels.pptx
A 2-year project that the sensors and circuit group at UCL have been involved in, has come to an end with successful results and promising roadmap for the future work. Dr Amin Amiri and Prof Paul Brennan worked on the Phased Array Gateway and Satellite Tracking project in collaboration with three other companies. The project outcome showed a successful adaptive combining of antenna elements for simultaneous coherent transmission and reception of satellite signals at Ka-band.
The UCL sensors and circuits group recently visited Edinburgh for the 2019 EMSIG event. Posters were presented by the RAs and PhDs and Alvaro Arenas Pingarron won an award for the PhD poster competition. See the photos below!

The UCL Radar group recently attended successful NeXtRAD trials in South Africa. These trials were aimed at deploying 3 radar nodes along the coastline in South Africa to capture data of drones, boats and calibrations spheres as well as sea clutter measurements across a number of bistatic angles. This work was supported by researchers at University of Cape Town, the Institute of Maritime Technology (IMT) and CSIR.
Some team members recently attended a Microlocal Analysis (MA) applied to real-world imaging problems workshop at the Alan Turing Institute organised by Dstl. The first day focused on how MA could help with Synthetic Aperture Radar (SAR) image formation and processing. Below is an image of Dr. Francis Watson presenting for Dstl on the topic of SAR.
Some members of UCL Radar group recently visited the RAF Museum in North London. This was a great visit for the team and one that was well timed in the 100th year for the RAF. Below are some photos from the visit.
The UCL-Birmingham Inter-University Symposium was held at Heythrop Park in Oxfordshire. As the two top universities in the UK for radar research it was decided to hold a joint symposium on the latest research projects on-going at both universities. The posters session was then followed by a team bonding event which all the PhDs and Postdocs were made into teams competing against each other. In the evening over dinner and a quiz the winners of the poster session were announced:
- 1st Ben Willetts
- Joint 2nd Veronika Yordanova
- Joint 2nd Qingchao Chen
Over all it was a fantastic event and all who attended really enjoyed it. Here are some photos to prove it!
The most recent seminar given to the Radar Group is now available on the YouTube channel. This was given by Dr. Bo Tan on the subject of “Interpreting Human movements with indoor RF”.
We have two new uploads to the Radar Group YouTube channel today. One is from Dr. Matthew Ritchie and another from Mr. Yu Liu a PhD student within the radar group.
Dr. Ritchie speaks about recent experiments performed using the NetRAD radar system looking the radar signatures from micro-UAVs and birds. This work is part of a collaboration with FFI, Norway and preliminary results will be published at the IEEE Radar conference 2016.
The second seminar is on the topic of Wireless Mesh Network security and covers typical attacks and counter-attack methods within these types of networks. 19/02/16
Todays seminar was given by Federico Lombardi. He presented some recently obtained results from measurements of different models of landmines and explained the key features seen in the data. Enjoy!
Today at UCL Prof. Hugh Griffiths, Dr. Matthew Ritchie and Dr. Francesco Fioranelli were privileged to host VIP visitors from Dstl, US DoD, ONR-G and US Army research, including Mr. Stephen P. Welby (Assistant Secretary of Defense for Research and Engineering). The guests were introduced to some of the innovative research that UCL is currently working on ranging from multistatic radar sensors, wind turbine measurements, human micro-Doppler, micro-Drone and through wall radar experiments.
A paper presenting results on personnel recognition based on micro-Doppler signatures collected by multistatic radar has been published as a featured contribution in the latest issue of Electronic Letters (volume 51, issue 25). This research work is being carried out by Research Associates Dr Francesco Fioranelli and Dr Matthew Ritchie, with Prof Hugh Griffiths, and it uses the multistatic radar system NetRAD developed here at UCL. The work shows highly promising results in the use of features to recognise different people from their individual walking gait, which can be successfully captured by radar sensors and analysed. Potential applications include recognising individuals and in determining whether or not they may be armed.

Last week, Matt Ash completed the installation of Geodar HD at the Vallee de la Sionne avalanche test site in Switzerland. The phased array radar will operate autonomously throughout the winter recording naturally occurring avalanches in the valley. The aim of the project is to improve our understanding of avalanche dynamics through high resolution radar measurements. The radar was developed by Matt, Mandana Ardeshir-Tanha, and Paul Brennan and funded by EPSRC.
Dr Amin Amiri from the radar group visited the Imperial War Museum (http://www.iwm.org.uk/visits/iwm-london) in London in order to take RCS and dielectric measurements of real landmines (de-activated of course). This is part of the continued Ground Penetrating Radar (GPR) and de-mining projects within the UCL Radar group. Below are some images of the mines that were measured
Today's seminar was given by Dr. Francesco Fioranelli on the subject of “Experimental analysis of multistatic multiband radar signatures of wind turbines”. It can be seen here:
Today's seminar was given by Dr. Matthew Ritchie on the subject of “Countering Micro-UAVs using Micro-Doppler and Multistatics”. It can be seen here:
Mark Davies recently gave a IEEE AES Society presentation to the Radar group on the topic of FOPEN (Foliage Penetrating Radar).
The recent Friday seminar was given by Federico Lombardi and the presentation is now available on the UCL Radar Group Youtube channel here:
Recent through the wall experiments were performed at the Shenley trials site by the UCL Radar Group and the Crime Science department. For these experiments both an active and a passive radar system were used to evaluate the detection of individuals walking in a house. Successful detection of both single and multiple people as well as their Doppler characteristics were measured. Below is an image of the active radar system, Soprano, deployed outside of the house wall.
