Signal Intelligence

There is a difference between Electronic Warfare (EW) and Signal Intelligence (SIGINT).

  • EW can be considered an ‘offensive strategy’ – where our military jams the transmissions of the enemy, and can be used for Cyber-warfare.
  • SIGINT can be considered a ‘defensive strategy’ – where our military eavsdrops, detects, and anlyzes the transmissions of the enemy.

Signal Intelligence requires RF instrumentation that provides a wide RF Bandwith (BW), broad Instantaneous BW, improved Displayed Avg Noise Level (DANL), along with Real-time (RT) Signal Analysis with the fastest Probability-of-Intercept (POI) to capture intermittent and low energy interference.

  • Wide RF BW ensures monoriting more of the occupied RF Spectrum
  • Broad Instantaneous BW to analyze more of the RF Spectrum all at once
  • Improved DANL enables capture of low energy interfence near the Noise Floor
  • RT Signal Analysis with fast POI enables ‘gap-less’ acquisition of intermittent signals

Combining the NI PXIe-5668 and PXIe-7976R provides 63,550 DSP Slices for unmatched Signal Processing capability.

  • POI for the PXIe-5668 and PXIe-7976R is 20 μsec to meet ITAR regulations.
    If you require better than this specification please contact NI, which can provide algorithms that improve upon this time to below 1 μsec.
  • Phase Coherent Synchronization capable for MIMO and Radar Prototyping
  • Add NI RAID-Array for Full-bandwidth Streaming with Record & Playback
