investigating SAM detection Range Lower Hemisphere vs Upper Hemisphere (SA6)

[PMcG]

Hi 

I noticed that the ["detectionDistanceAir"] for the SA-6 is the same for Lower Hemisphere and Upper Hemisphere (46811.82421875). I`m assuming Lower Hemisphere is low altitude and Upper Hemisphere is High altitude, if that's the case, I would think that lower hemisphere would have a shorter detection distance than Upper hemisphere due to the curvature of the earth?

Your assumption may not be correct since the SA-6 is a low-to-medium altitude system. I'm not sure what the numbers are describing but I doubt the lower hemisphere number would need to be lower. In your conceptualization that number would always be different depending on the distance to the horizon. It would be different in flat vs mountainous terrain, for example.
