Abstract

Temperature, atmospheric pressure, and vapor pressure affect electromagnetic propagation. ​For radars, variations in electromagnetic propagation can cause a radar target (e.g., aircraft) to shift in its apparent position, resulting in misrepresentation of the target’s position on the radar display​. These variations can be forecast using atmospheric profiles from Numerical Weather Prediction (NWP) and ray tracing software. Evaluation and quantification of differences between forecasted and analyzed electromagnetic propagation conditions using ray tracing techniques and atmospheric conditions derived from the Rapid Refresh (RAP) model will provide guidance regarding Detect And Avoid (DAA) performance requirements.
