NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.
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.
