- the vertical projection of the defined location 12 corresponding location 18 are localized. In this way, the user can, for example, make holes through the wall 10, where he knows in advance, where the drill on the opposite side 16 of the wall 10 exits.
- a high-frequency transmitter is held on the wall 10 on one side 14 and fixed thereto.
- a wall mount, an adhesive device or a tripod for the high-frequency transmitter can be provided.
- the high-frequency transmitter has a high-frequency transmitter 20 with a transmitting antenna, which preferably points in the direction of the wall and radiates a high-frequency measuring signal 22 into the wall 10.
- the measurement signal 22 is in the gigahertz frequency range, with measurement frequencies that are typically in an interval of 1 GHz to 5 GHz.
- one or more measurement frequencies from a frequency interval of 1.5 GHz to 3.5 GHz are used in the method according to the invention.
- the directed high-frequency signal 22 of the high-frequency transmitter 20 is subsequently detected on the first side 14 of the wall 10 facing away from the second side 16 of a high-frequency receiver 24.
- the high-frequency receiver 24 has a
- Receiving unit with one or more receiving antennas, which receive the measuring signal 22 and forward to an evaluation of the meter 24.

- the receiver 24 may, for example, also be a high-frequency locating device which can be switched into the pure receive mode by means of suitable software or hardware circuitry.
- FIG. 2 illustrates some of the significant steps of the high frequency frequency material penetrating positioning method of the present invention.
- a radio frequency unit 32 of a radio frequency transmitter 20 generates microwaves in the gigahertz range, such as by FMCW or pulsed radar techniques.
- the transmitter can therefore generate one or more individual frequencies (FMCW method) or a broadband pulse spectrum (pulse radar).
- the micro-wave signals thus generated, which form the measuring signal 22 of the method according to the invention, are emitted via an antenna arrangement 34, which comprises at least one antenna. If the high-frequency transmitter 20 on one side 14 of a workpiece, for example a
- the microwaves penetrate as directed radio frequency signal 22 the wall and can be detected by a Hoch ⁇ frequency receiver 24 on the other side 16 of the wall.
- the radio-frequency receiver 24 has a receiving antenna arrangement 36 and a radio-frequency receiving section 38, which processes the received radio-frequency signal and displays it in an intuitively catchy manner, for example by means of a display device.
- the penetration site or the projection point 18 of the measurement signal can thus be located on the second side 16 of the wall 10 facing away from the high-frequency transmitter 20 and marked by suitable means on the wall surface. For example, under too
- bores are made by reinforced concrete, in which the user knows in advance, where the drill exits on the side facing away from the wall to be drilled. Due to the frequency range used, the method according to the invention enables the localization of the projection position with high accuracy.
- Fig. 3 shows an alternative embodiment of the method according to the invention.
- a measuring device 100 is used which is both high-frequency transmitter 120 and high-frequency receiver 124.

- a reflector means 126 for example, a passive or even an active reflector, which reflects the received signals of the transmitter and thus forwards to the high-frequency receiver.
- a reflector means may be formed as a SAW element (Surface Acoustic Wave).
- the measurement signal 122 returned by the reflector means 126 can be arranged in the same frequency range or else in a shifted frequency range.
- transponders can be used as reflector means 126, which detect and process the measurement signal 122 penetrating the wall and, after an internal delay time, send a response signal 123 correlated with the detected original measurement signal 122 back through the wall 10.
- Both passive and active transponders can be used, i. those without or with independent energy supply.
- Such a transponder generates after a certain internal runtime, which is known, a new signal, which it emits via its own antenna, for example in the ISM band at a frequency of 2.45 GHz. This newly generated signal in turn penetrates the wall and can be detected by the high-frequency receiver 124 of the measuring device 100.

- the signal received via an antenna device 140 from the transponder 128 is passed via a coupler 142 or a circulator to a receiving amplifier 144. After amplification, the signal passes through an RF switch 146, which is through-connected in the idle state, to a pulse detector 148. This delivers an output voltage which is proportional to the input power.
- Pulse detector 148 is amplified in a LF amplifier 150. In a subsequent comparator, a digital signal is again generated from the analog voltage signal. In a monoflop 154, the relatively short comparator signal is brought to a defined length. This signal is used by means of the delay elements 156 and 158 to blank the receiving stage and transmit pulse generation. The from the
- Transmit pulse generator 160 generated signal is brought back to the antenna device 140 via the coupler 142 and a circulator and sent back to the measuring device 100 through the examined wall.
- Fig. 5 shows an alternative realization possibility of the transponder 128.
- a scanner is used.
- the clock in which the sampler is controlled Via a microcontroller 164, the clock in which the sampler is controlled, regulated such that sets a maximum voltage at the output of the scanner.
- the clock of the microcontroller and the clock of the measuring device 100 run synchronously with one another, but shifted by the transit time of the measuring signal. In this way it is possible to localize the fürdringungsort of the measuring signal and also, if desired, also make a wall thickness measurement. Since the signal that controls the scanner is also sent directly, the response of the transponder takes place with minimal delay.
- FIG. 6 A further alternative for the basic structure of a transponder for the method according to the invention is shown in a simplified manner in FIG.
- the received measurement signal in the transponder 128 is amplified by an amplifier 170 and, after a certain time delay, which is realized via a delay element 142, again via the coupler 142 and the
- Antenna device 140 emitted in the manner of a ring amplifier.
- the extension of the transponder by, for example, an AC sensor (50 Hz sensor) and / or an inductive sensor is also possible.
- an additional function of the transponder allows the user to exclude damage to, for example, a power line, even on the side facing away from the measuring device 100, for example a wall.
- High-frequency locating device 100 which can be switched by means of suitable software or hardware circuit in the receiving mode and so can indicate, for example, the position of the hole and the wall thickness.
- a receiving device for the method according to the invention can be advantageously use a locating device on a high frequency basis, as described for example in the application DE 10207 424 Al the applicant.
- the method according to the invention is not limited to the prediction of drilling channels in a wall.
- the method according to the invention can already be integrated into corresponding devices, such as a drilling tool.
