Effects of Earth's Curvature
on estimating a target's position

One must account for the curvature of the earth when determining the altitude of a target. Distant targets, which are close to the ground, cannot be seen by a radar because they will be below the horizon.

The height of a distant target that is above the horizon will be underestimated if the curvature of the earth is not taken into account.
