How many microseconds does RF take to travel one radar mile?

Explanation:
RF travels at the speed of light, so the time to cover a distance is the distance divided by c. In radar, range is determined from the pulse’s round-trip time (there and back) because you wait for the echo. A radar mile is defined so that the one-way travel time for that distance is about 6.18 microseconds. Since the measurement is round-trip, you double that time: 2 × 6.18 µs = 12.36 µs. So the RF takes 12.36 microseconds to travel one radar mile (there and back).
