where r = slant distance from the centre of the antenna to the body head.
It determines range by slant distance calculation based on relative signal amplitude, a method limited by the fact that transponder power output isn't a constant, thus it's difficult to distinguish a powerful transponder at great distance from one of lesser power closer to the receiving antenna.
All that matters is the straight horizontal distance, not the slant distance up or down.
