A radar transmits a pulse of RF Electrical power with the pace of sunshine. This pulse collides by having an object and is also reflected being an echo to the radar. The radar measures enough time for your pulse’s spherical trip from your antenna for the goal and again again. By halving this, the radar can determine the focus on’s selection.
