Military Radomes

Hardware-in-the-Loop Testing

Whether you prefer the electronically calibrated antenna or null search BSE test method, when it comes to testing the accuracy of military radomes, we have you covered. Choose NSI-MI for reliable and accurate testing of your military radomes. Our features and capabilities guarantee precise measurements and superior performance.


Features
  • Supports either electronically-calibrated antenna or null search boresight sight error test method
  • Beam deflection error and transmission efficiency measurements at multiple frequencies are accomplished in one radome scan without manual intervention
  • Using the calibrated antenna approach, typical test time for simultaneous beam deflection error and transmission efficiency is approximately one hour
  • Antenna is oriented within radome as it would be on aircraft
  • Integrated Position Controller's (link this to the IPC page) coordinated motion used to ensure that the radome/antenna polarization relationship is the same as that seen in use on the aircraft, and so that the feed polarization is coordinated with the AUT as needed to maintain polarization alignment
  • Data post-processing and reporting in test positioner roll/azimuth coordinates or aircraft elevation/azimuth coordinates
  • Innovative cable management design essentially eliminates moving cables LO power to signal and reference mixers automatically varied with frequency to continually optimize linearity of the receiver
  • Full suite of pattern distortion data collection and analysis
