1. A method for operating a sensor arrangement having a control unit and a plurality of sensors, which are arranged in at least one group, wherein the sensors are connected to a common electrical supply, in particular via the control unit, the method comprising:
emitting sensor signals using the sensors, wherein the sensors of each group emit their sensor signals in their respective group transmission phase;
receiving echo signals based on reflections of the sensor signals;
transmitting the received echo signals from the sensors to the control unit; and
identifying interference in the received echo signals from the at least one group based on a comparison of at least two of the received echo signals from the corresponding group.
