Welcome to the IRCTR

In 1994, IRCTR, the International Research Centre for Telecommunications and Radar, was established as part of the Faculty of Electrical Engineering, Mathematics and Computer Science of the Delft University of Technology. IRCTR is a project-driven institute and performs research projects in the field of telecommunications and radar. The projects attract many MSc's, PhD's and Post-docs from the Netherlands, as well as from abroad.

Netherlands government, industry and (semi)-governmental organisations support IRCTR since its founding. Research highlights strategy and road maps are regularly reported and discussed with the industrial Advisory Board. At present, the Board is composed by representatives from Thales NL, TNO, CHL Netherlands, Dutch Space and ENRAF.

Many national and international co-operative research projects with industry, institutes and universities exist. Today there are 73 actualized agreements with national and international universities and organisations. Our span of research control has been extended tremendously because of contributions from the guest scientists and co-operations with external partners.

The research is carried out in 2 sub-centres and focuses towards the specific areas:

Centre for Radar and Navigation

  • antennas and propagation
  • radar design, technology and systems
  • microwave remote sensing
  • navigation

Centre for Wireless Personal Communications

  • telecommunication technologies and systems
  • wireless and mobile communications
  • telecommunications networks, architecture and services


We have got a leading scientific and technological position on Ultra Wide Band Ground Penetrating Radar and on Frequency Modulated Continuous Wave Doppler Polarimetric Radar.

One of our challenging remote sensing activities for the coming years is our participation in national and international programmes on atmospheric research in relation to climate change. For validation of our fundamental results in atmospheric remote sensing we play an important role in the Cabauw Experimental Site for Atmospheric Remote Sensing.

The navigation research is known for contributions on integrated aeronautical navigation combined with accurate and reliable 4D positioning determination.

The wireless and mobile communications research has got international recognition for breakthroughs in personal networks. The radio technology and system research covers the development of state-of-the-art demonstrators.

The research on telecommunications networks, architecture and services is characterised by on the edge results to gain detailed knowledge on the complex structure of and the interaction in large telecommunication networks aiming performance improvements by optimizing algorithms, protocols and control rules.

We strongly contribute to the research on Information and Communication Technology coordinated nationally via the 3 Netherlands Technical Universities institute.

Extensive descriptions of ongoing research are given in the annual reports.

Research facilities
IRCTR is known for its outstanding radar facilities on the roof of the almost 100 m tall Faculty building as well as its Ultra Wide Band antenna, component and system labs and its Telecom Networks lab. An up-to-date simulation and experimental mm-wave facility is fully operational and has been installed inside a conditioned room connected with an anechoic chamber, important for our antennas and applied electro magnetic research.

After 10 years IRCTR was assessed in 2005 by an independent international committee, chaired by the Faculty dean. The committee comprised 12 evaluators from all over the world. Marks were given for 'accomplishments', 'innovative aspects', 'international ranking', 'realization of objectives' and 'overall appraisal'. On a scale where 5 is excellent and 1 is most negative the mean mark was 4.4. IRCTR is proud of this result.
