A finite amount of time is required for a signal to travel from one place to another. In a vacuum, electromagnetic energy travels at 2.9979*108 m/s. The following equation holds for signal propagation time in a vacuum, where the dielectric constant is 1.
If a radar type system is being evaluated where a round trip out and back needs to be accounted for, then double the distance figure. A "radar mile," which is a nautical mile out and a nautical mile back, is 12.36 μs.
Here is a 1-way propagation time calculator.
