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 distance and speed to a reflective target, such as a metal corner reflector. With typical ranges up to 50 meters (depending on the target’s RCS), it offers very high update rates and cost-effective installation. Common applications include crane and machinery positioning, presence detection, level probing, and object detection.
