The best way to get a feel for the radar horizon is to derive it. This problem does require some algebra. If you are familiar with algebra, try to do the derivation. If not, we suggest, you read through the solution to see how the derivation is done. Hints are available. You can also use the horizon calculator
For a sensor at height h, with the radius of the earth represented as rearth, the distance to the horizon can be approximated as
| Distance to the horizon R = (2·rearth·h)0.5 |
Derive the equation.
