Antenna Test Facility


  • NEAR FIELD TEST RANGE

    • It is the near field measurement system which is a unique & indigenously developed facility for testing of antenna (especially radars) by using pulsed FMCW /Chirped pulse.

    The system is capable of antenna pattern measurement for radar systems, and can be a generalized one with NF measurement systems upgraded with Chirp / FMCW source.
