FARAD: Flying Aircraft Radar Signature Acquisition and Determination

FARAD is a flexible radar system which is designed to perform dynamic Radar Cross Section (RCS) measurements of stealthlike flying targets. The system is customizable and expandable and only requires a short time to acquire accurate measurements. The radar, tracking equipment and the cabin for its operators and control and monitoring equipment is all designed for outdoor use, is self-powered, easy to deploy and fully transportable.


  • Embedded target tracking capability optimized for short range RCS dynamic measurement of flying targets. When being measured, the aircraft flies planned trajectories and is automatically tracked by FARAD.
  • Allows very fast operation and provides highly accurate data.
  • Includes powerful post processing capabilities integrated in a unique software tool and database capability.
  • High sensitivity as a result of extremely fast waveform generation (Direct Digital Synthesizer chirp) and the use of coherent and non-coherent integration.
  • FARAD is highly transportable and fast and easy to set up without the need of any preparation at the test site. This minimizes service outages and time delays, and reduces the installation and operational manpower needs.

Composition - System Breakdown

FARAD consists of two modules which are transportable by a single van and trailer:

  • The antenna subsystem is mounted on an equipment trailer and includes an RX/TX radar antenna assembly, target tracking equipment and positioning equipment.
  • The van houses the control equipment and post processing computers.


  • Target tangential speed: 250m/s
  • Frequency range: 8.5 – 10.5 GHz
  • Polarization matrix: HH or VV
  • Built-in radar tracking for azimuth angle, range and Doppler
  • Can be slaved to an external tracking system (e.g. ADSB)
  • Sensitivity: -30 dBsm @ 10 km
