High FreqUency oveR The Horizon sensors’ cognitivE netwoRk.

The iFURTHER project aims to address wide area air and sea covert surveillance, by developing new concepts of Over-The- Horizon radar to be integrated into a collaborative network of high-frequency sensors. This project will therefore focus on a cognitive network of high-frequency radars as a disruptive future defence capability to protect the EU. The main objectives of this project are:

  • Detect and track air and sea targets at long range (over the horizon), far beyond currently existing systems, by using the reflections of skywave and surface-wave propagated signals
  • Fill gaps and extend the current EU air and sea radar coverage by introducing a multistatic sensor configuration supported by ad-hoc network protocols and an appropriate infrastructure for synchronization and coordination of sensors (e.g., C2)
  • Implement cognitive radar management systems to optimise operational parameters in real time and as a function of environmental conditions (e.g., the state of the ionosphere), based on robust ionospheric models and sounding protocols (not excluding the development of ionospheric sensors)
  • Implement advanced signal processing techniques to improve over-the-horizon detection and track performance as well as target localisation capabilities
  • Utilize available non cooperative illumination and apply cognitive features at network level to develop new techniques for optimized use of the electromagnetic spectrum and passive processing.
