Applications

  • Electronic Warfare - Visualize and post process broad segments of the battlefield spectrum to design robust communications networks.
     
  • Wireless Communications - Capture, identify and play back waveforms or create new ones fundamental to the testing and development of satellite and terrestrial, voice, data and telemetry equipment and networks.
     
  • Spectrum Management - Monitor spectrum usage and supplement the use of spectrum snapshots and tedious power surveys with long duration, geo-tagged, time-stamped spectral recordings.
     
  • Radar - Capture wide bandwidths over extended time periods to analyze radar effectiveness. Create and test new waveforms to improve performance.
     
  • Surveillance - Determine usage patterns, intercept transmissions and correlate data files to receiver locations for military, drug interdiction and homeland security applications.
