1: Weak Object (Radar cross section = 0.25 m2)
2: Car (Radar cross section = 3 m2)
3: Large Truck (Radar cross section = 50 m2)
1–4: Indicates sensitivity level
4: Passenger Train (Radar cross section = 300 m2)
NOTE: The effective beam pattern depends on the sensitivity level and target properties.
Windows
The R-GAGE sensor can be placed behind a glass or a plastic window, but the configuration must be tested and the
distance from the sensor to the window must be determined and controlled prior to installation. There is typically a 20%
signal reduction when the sensor is placed behind a window.
