Claims (20)

1.264696/
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.
3. A processing system according to claim 1 or claim 2, wherein the radar signals comprise 3D radar signals, the processor is configured to identify the locations associated with the at least one first body in 3D, and the processor is configured in the configuration mode to determine a plane of best fit to map the identified locations onto the plane for the determination of the virtual fence in the plane, and in the monitoring mode to identify locations associated with the second body in 3D and to map the locations associated with the second body onto the plane for the determination of whether the second body is inside or outside the virtual fence in the plane.
4. A processing system according to any preceding claim, wherein the topology of the surface is determined also using additional locations of the single first body within a closed region defined by the virtual fence. 29 264696/
5. A processing system according to any preceding claim, wherein the locations associated with each of the at least one first body are locations of a radar measurement centre of the or each first body.
6. A processing system according to any preceding claim, wherein the processor is configured to receive an input from a user interface to modify at least some of the coordinates determined from the identified locations to define the virtual fence.
7. A processing system according to any preceding claim, wherein the coordinates define the virtual fence.
8. A processing system according to any preceding claim, wherein the processor is configured in the configuration mode to define at least one further virtual fence, and in the monitoring mode to detect the location of the second body to determine if the second body is inside or outside the at least one further virtual fence.
9. A processing system according to claim 8, wherein the processor is configured to determine the at least one further virtual fence based on a modification of said coordinates for defining the virtual fence.
10. A processing system according to claim 8, wherein the processor is configured to determine the at least one further virtual fence by processing the radar signals to identify locations associated with at least one first body to provide coordinates of the at least one further virtual fence.
11. A processing system according to any one of claims 8 to 10, wherein the processor is configured to generate a first indication if the second body is determined to be inside the virtual fence and at least one second indication if the second body is determined to be inside the at least one further virtual fence.
12. A system for defining a virtual fence and for detecting a body inside or outside a region of interest defined by the virtual fence, the system comprising: a processing system according to any preceding claim; and a radar antenna configuration to emit radiation and detect the emitted radiation reflected from the at least one first body and the second body as radar signals. 30 264696/
13. A method of defining a virtual fence and for detecting a body inside or outside a region of interest defined by the virtual fence, the method comprising: receiving radar signals from a radar antenna configuration; in a configuration mode, processing the radar signals to identify locations that lie along a boundary of a region of interest across a surface and are associated with a first body, and processing the identified locations to determine coordinates for defining the virtual fence; and in a monitoring mode, processing 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, in the configuration mode, a topology of the surface is determined using the identified locations associated with the at least one first body in 3D and the known height.
14. A method according to claim 13, including generating an output when the second body is determined to be inside the virtual fence.
15. A method according to claim 13 or claim 14, wherein the coordinates define the virtual fence.
16. A method according to any one of claims 13 to 15, wherein, in the configuration mode at least one further virtual fence is defined, and in the monitoring mode the location of the second body is detected to determine if the second body is inside or outside the at least one further virtual fence.
17. A method according to claim 16, wherein the at least one further virtual fence is determined based on a modification of said coordinates for defining the virtual fence.
18. A method according to claim 16, wherein the at least one further virtual fence is determined by processing the radar signals to identify locations associated with at least one first body to provide coordinates of the at least one further virtual fence. 31 264696/
19. A method according to any one of claims 16 to 18, including generating a first indication if the second body is determined to be inside the virtual fence and at least one second indication if the second body is determined to be inside the at least one further virtual fence.
20. A carrier medium carrying processor implementable code, which, when executed by a processor, causes the processor to implement the method of any one of claims 13 to 19. Roy S. Melzer, Adv. Patent Attorney G.E. Ehrlich (1995) Ltd. 11 Menachem Begin Road 5268104 Ramat Gan
