2.CLAIMS 1. A processing system for defining a virtual fence and for detecting a body inside or outside a region of interest defined by the virtual fence, the processing system comprising: an input to receive radar signals from a radar antenna configuration; and a processor to operate in a configuration mode to process the radar signals to identify locations that lie along a boundary of a region of interest across a surface and are associated with at least one first body, and to process the identified locations to determine coordinates for defining the virtual fence, and to operate in a monitoring mode to process the radar signals to detect a location of a second body on the surface to determine if the second body is inside or outside the virtual fence wherein the identified locations associated with the at least one first body are associated with a single first body and are at a known height above the surface, and the processor is configured in the configuration mode to determine a topology of the surface using the identified locations associated with the at least one first body in 3D and the known height. 2. A processing system according to claim 1, wherein, in the monitoring mode, the processor is configured to process the radar signals to detect the location of the second body traversing the surface by determining that the second body is moving and detecting the location of the moving second body.
