Transmitter - Transmits radio waves

Antenna - Guides radio waves into positioned direction
Waveguides - Transmission lines
Antenna - Guides radio waves into positioned direction
Duplexer - Grants the radar to pick up new waves and to transmit waves at the same time
Receiver - Detects incoming waves from object(s)
Threshold decision - Compared to receiving signals, if receiving signals surpass the threshold, then the signals are accepted

Long exposures to radio waves may cause cancer. However, radio waves are the least harmful type of electromagnetic waves are radio waves. Therefore, harmful impacts from radio waves are the lowest, compared to the other types of electromagnetic waves.

Airport Radar Systems detect objects, along with the distance and position of the objects within a specific radius. The radar releases radio waves, and, once an object is hit by these radio waves, the radio waves bounce back off with a higher frequency from the object and the Radar system gathers these electromagnetic waves and uses the data to find the distance between the radar and the object and the position of the object within a specific radius.
