摘要：
In a method and a measuring device for metal detection with the use of a coil arrangement the spatially offset transmitting coils are controlled with pulse sequences of different pulse patterns. The receiving coils associated with the transmitting coils are scanned with respect to the received measuring signals with a scan pattern corresponding to the respective associated pulse pattern. It is therefore possible to control simultaneously all transmitting coils and to provide a spatial determination of a metal object located in a throughgoing region of a gate frame.
