$\red{ \boxed{\texttt{Radar}}}$

• RADAR is fundamentally an electromagnetic sensor used to detect and locate objects. Radio waves are radiated out from the radar into free space. Some of the radio waves will be intercepted by reflecting objects (targets). The intercepted radio waves that hit the target are reflected back in many different directions.
• An example of radar is the device highway patrol officers use to detect people who are driving too fast.
