Abstract

In a method for locating objects enclosed in a medium, a detection signal is generated by at least one capacitive sensor. The detection signal penetrates the medium that is to be analyzed in such a way that information is obtained about the objects that are enclosed in the medium by evaluating the detection signal, particularly by measuring impedance. In order to evaluate the detection signal, an algorithm is used that separates the measured signal into signal parts originating from the enclosing medium and signal parts originating from the object enclosed in the medium. A measuring device carries out the inventive method.
