Information

RADAR stands for‘Radio Detection And Ranging’ and is an active transmission and reception method in the microwave GHz range. Radar sensors are used for contactless detection, tracking, and positioning of one or more objects by means of electromagnetic waves.

 

 

The radar antenna emits a signal in the form of radar waves, which move at the speed of light and are not perceivable by humans. When the waves hit objects, the signal changes and is reflected back to the sensor – similarly to an echo. The signal arriving at the antenna contains information about the detected object. The received signal is then processed in order to identify and position the object using the data collected. In a second step, it is possible to emit a pulse to trigger a reaction.
