摘要： An apparatus includes a plurality of sensor modules that are disposed at spacings with respect to one another, each sensor module having a local oscillator device. The oscillator device generates an oscillator signal that is passed on to a transmit/receive device, and the oscillator signal is radiated. The transmit/receive device is set up such that it can receive signals reflected from the object. A phase detection device is coupled at one input to the oscillator device and at a second input to the transmit/receive device. Based on the oscillator signal and the received reflected signals, the phase detection device determines a phase signal. A control and signal-processing device determines, based on the spacings of the sensor modules with respect to one another and the phase signals, a direction of the object with respect to the sensor module.
