Parasol Defense - The Passive Radar System for Covert 3D Positioning


In collaboration with the Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR), we have been jointly developing the passive radar system for the detection of aircraft and the localization of moving objects on the ground for over 15 years. Our proven and tested passive radar system, which can be used both stationary and mobile, offers a wide range of applications:

  • Covert detection of moving objects from ground level up to heights of 10,000m and beyond
  • No transmission radiation (utilizes existing radiation or through the use of its own sacrificial transmitter)
  • Coverage of 450km² of airspace/ground monitoring (3D detection of moving aerial and ground objects starting from 0.5m² radar cross-section)
  • Low maintenance requirements
  • Over 15 years of experience
  • Both mobile and stationary units
  • Options for purchase and rental
  • Provision of an online live-tracking interface

We are at your disposal and ready to assist you. Please feel free to contact us.
