A device for detecting signals is disclosed. In at least one embodiment, the device includes at least four detector elements for receiving the signals and converting them into useful signals, each being connected via at least two lines to at least one signal processing unit. Each detector element includes a polarity reversal unit by which polarity reversal of the useful signal of the respective detector element can be performed. The signal polarity reversal logic is unambiguously spatially direction-dependent within the detector array. An advantage of the device of at least one embodiment is that for signals to be received simultaneously by way of two detector elements, the detector elements involved become unambiguously identifiable by the polarity reversal of the useful signal.
