Abstract: A radar detection system can be calibrated by a method which includes selecting location indicators with corresponding locations. A transmitter of a sensor emits a radar signal to the location of each of the location indicators. The radar signal is reflected off of a target at the location of each of the location indicators. The radar signal which has been reflected off of the target is received with a receiver of the sensor. The location of the target at each of the location indicators is communicated between the sensor and a controller. Locations which define a protected region are selected with the controller. The controller designates the protected region, thereby calibrating the radar detection system such that the radar detection system is capable of detecting an object in the protected region. The calibrated radar detection system can detect targets in an operational mode.
