What Is Beam Height?
How high above the ground the radar beam is at a given distance. Because the Earth curves away, far-off storms are only seen high up. In technical terms: The height of the radar beam centerline above ground, depending on elevation angle, range and refraction.
Beam Height In Plain English
How high above the ground the radar beam is at a given distance. Because the Earth curves away, far-off storms are only seen high up.
The Technical Definition
The height of the radar beam centerline above ground, depending on elevation angle, range and refraction; under the standard 4/3 effective earth-radius model a 0.5 degree beam is near 1 km at 60 km, 3 km at 185 km and about 5 km at 250 km range.
