Abstract

The invention relates to a method for the material-penetrative localization of a measurement signal, in particular a material-penetrative positioning method for use on walls, ceilings, and floors.

According to the invention, a high-frequency transmitter (20, 120) emits a measurement signal (22, 122) in the gigahertz frequency range, which penetrates the material (10) at least once and is detected by a high-frequency receiver (24, 124) in order to locate the penetration position (18).

The invention also relates to a device for carrying out the method.

Claims

1. A method for the material-penetrative localization of a measurement signal, in particular a material-penetrative positioning method for use on walls, ceilings, and floors,

wherein

a high-frequency transmitter (20, 120) emits a measurement signal (22,122) in the gigahertz frequency range, which penetrates the material (10) at least once and is detected by a high-frequency receiver (24, 124) in order to locate the penetration position (18).

2. The method as recited in claim 1,

wherein,

the measurement signal (22, 122) has more than one measurement frequency.

3. The method as recited in claim 1,

wherein

the measurement signal (22, 122) is directed.

4. The method as recited in claim 1,

wherein

one or more measurement frequency/frequencies in an interval of 1000 MHz to 5000 MHz, and preferably in an interval of 1500 MHz to 3500 MHz are used.

5. The method as recited in claim 1,

wherein

the measurement signal (22, 122) is generated using the FMCW method in the gigahertz frequency range.

6. The method as recited in claim 1,

wherein

the measurement signal in the gigahertz frequency range is generated using a pulsed-radar method and is launched into the material.

7. The method as recited in claim 1,

wherein

the high-frequency transmitter (20) and the high-frequency receiver (24) are operated on two different surfaces (14, 16) of the material (10) which face each other.

8. The method as recited in claim 1,

wherein

the high-frequency transmitter (120) and the high-frequency receiver (124) are operated on the same first surface (14) of the material (10);

the measurement signal (122, 123) from the high-frequency transmitter (120) is reflected back to the high-frequency receiver (124) by a reflector means (126) which is movable on a second surface (16) of the workpiece (10).

9. The method as recited in claim 8,

wherein,

the reflector means (126) include a SAW (Surface Acoustic Wave) element.

10. The method as recited in claim 8,

wherein,

the reflector means (126) include a transponder (128).

11. The method as recited in claim 8,

wherein

the high-frequency transmitter (120) and the high-frequency receiver (124) are operated in the same device (100), in particular a hand-held device.

12. The method as recited in claim 1, wherein

the localization of the measurement signal (22, 122, 123) which penetrated the workpiece (10) can be carried out using a signal strength display of the high frequency receiver (24, 124) and/or reflecting means (126).

13. A device for carrying out the method as recited in claim 1,

wherein

the device includes at least one high-frequency transmitter (20, 120) capable of being placed on a surface (14) of a material (10), and one high-frequency receiver (24, 124).

14. The method as recited in claim 13,

wherein

the high-frequency transmitter (120) and the high-frequency receiver (124) are operated in the same device (100).

15. The method as recited in claim 14,

wherein

at least the high-frequency receiver (124) includes a marking device for producing a mark on a surface (14, 16).
