Atmospheric Propagation

Atmospheric Propagation Branch

We have more than 55 years of expertise in electromagnetic (EM) propagation modeling, environmental data assimilation and C4I decision aids. 

EM propagation modeling of environmental effects on radiated frequencies from HF (2 MHz) to infrared (300 THz):

  • Marine
  • Terrain
  • Surface, airborne, satellite platforms
  • Spatially varying atmosphere and terrain
  • Interference/jamming with anomalous propagation
  • Ocean surface and terrain clutter

Surveillance systems and strike warfare:

  • Infrared search and track system - marine atmospheric modeling suite
  • Models and simulation for target detection and tracking
  • Small boat wake detection



Analysis of atmospheric, ionospheric, and surface parameters:

  • Temporal and spatial behavior
  • Joint probabilities
  • Statistical characterization of refractivity
  • Aerosol, molecular, and turbulence models for long-path propagation assessment
