Abstract (en)
[origin: WO2006045668A1] The invention relates to a device having a plurality of sensor modules (2, 2<SUP>1</SUP>,2<SUP>2</SUP>, 2<SUP>3</SUP>, 2<SUP>n</SUP>) which are disposed at distances d<SUB>1</SUB>, d<SUB>2</SUB> in relation to each other, every sensor module (2, 2<SUP>1</SUP>,2<SUP>2</SUP>, 2<SUP>3</SUP>, 2<SUP>n</SUP>) having a local oscillator device. Said oscillator generates an oscillator signal which is forwarded to a transceiver and the oscillator signal is scattered. The transceiver is adapted to receive signals reflected by the object. A phase detection device is connected with one input to the oscillator device and with the other input to the transceiver. The phase detection device uses the oscillator signal and the received reflected signals to determine a phase signal. A control and signal processing device uses the distances of the sensor modules to each other and the phase signals to determine a direction a<SUP>1</SUP>, a<SUP>2</SUP>, a<SUP>3</SUP>, a<SUP>n</SUP> of the object in relation to the sensor module.
