Operation
Sensor Description
The radar sensor transmits and receives a low power 5.8 GHz radar signal. It
processes the returned signal to determine if an object is within the detection area
and reports this to the driver via the rear sensor display. The sensor’s fast response
time allows the driver to respond to dangerous situations immediately.
The sensor has a maximum detection zone depth of approximately 15 feet (5
meters) from the face of the sensor. When the radar sensor detects an object within
its detection zone, a signal is sent from the sensor to the rear sensor display to warn
the driver of a potential collision.
The table below shows how object detection is report to and displayed by the rear
sensor display from the sensor.
