Pulsed Noise Radar Front-end Module at 94 GHz

Features
  • Powerful incoherent source
  • 1 Watt typical output power
  • High stability
  • 5 GHz white noise spectrum
  • No high voltage supply required
  • Compact solid state source

Applications

 

  • Ground control in airports and other facilities
  • Avoid collision systems
  • Precise distance measurement in dusty and/or humid atmosphere
  • Level sensing for any materials and liquids in tanks with foam/vapour
  • Robotic sensors

Description

     High power pulse noise source PNS series is used for the illumination of target. Noise nature of probing signal avoids the problem of interference. Image obtained by means of noise radar allows to recognize target better then the image obtained by means of coherent radar.
