wo α den horizontalen Abstand der beiden Stationen bedeutet und die reflektierende Fläche der Einfachheit halber parallel der horizontalen Oberfläche angenommen ist, was bei Grundwasser annähernd erfüllt ist.where α means the horizontal distance between the two stations and, for the sake of simplicity, the reflecting surface is assumed to be parallel to the horizontal surface, which is approximately fulfilled for groundwater.

Statt die Wellenlänge zu verändern, könnte man auch den Abstand der Stationen ändern. Dies würde aber die Beobachtung erschweren und außerdem leicht zu Täuschungen 35 .·, führen, da hierbei die Strahlenwege stetig in andere Gebiete verlegt werden würden. .Instead of changing the wavelength, you could also change the distance between the stations. However, this would make observation more difficult and also easily lead to deceptions 35. lead, since the radiation paths would be constantly relocated to other areas. .

The invention relates to a method for the detection of underground ore deposits and ground

■ ·. water level by means of electric waves and is based on the. Using the interference method.

Two antennas 5 and E are stretched out in parallel, close to the ground. If there is a reflecting surface below the ground, the reception effect in E is partly due to the reflected and partly to the direct. waves transmitted by the air. By changing the wavelength of the emitted radiation, you can • - without changing the distance between the transmitters
