Environmental Factors
You can specify or calculate the System Temperature and set Rain Model parameters locally. You can also choose a refraction model for your radar analysis.
Radar analysis uses geometric Line Of Sight (LOS) calculations in the access analysis to determine object visibility. Yet, when Use Refraction in Access Computations is selected on the Refraction properties page, all access computations for that radar are based on the refracted LOS, not the geometric LOS. This may enable a radar antenna to see over the horizon objects.
