1) Depending on the environment, the selected bandwidth mode, and the target‘s backscatter characteristics.
2) Error under consistent ambient conditions, depending on the measurement distance and the measuring mode.
3) Preliminary value
Multiple bandwidth modes can be selected in the device settings. The selection is limited by regional radio regulations.
Primary radar mode

In primary radar mode a single LPR®-1DHP-291 measures the distance and speed to a reflective object, typically a metal corner reflector. The range is typically 50 m but depends on the radar cross section (RCS) of the used target. The primary radar mode features very high update rates and enables a cost effective installation. Typical applications are positioning of cranes and heavy machinery, presence check, level probing and detection of objects.

Secondary radar mode

In secondary radar mode two LPR®-1DHP-291 measure the distance and speed between each other. The secondary radar mode features high ranges of up to 300 m and high update rates and ensures that the measurement is taken only to the partner unit. Typical applications are positioning of cranes and heavy machinery, process automation and collision avoidance.
