As Uman explains, a radar set can send out “electromagnetic pulses, which are reflected back by certain objects (e.g. metallic airplanes).” The pulses travel at 186,000 miles per second. So measuring the time that elapses between the emission of a pulse and when its reflection is received allows for the distance to be measured.
