Method and device for the position determination of objects by means of communication signals, and use of the device
First Claim
1. A method performed by a vehicle-to-X communication device being mounted in a vehicle for position determination of an object by means of a communication signal, comprising the steps of:
- providing a transceiver capable of wireless communication which transmits the communication signal, wherein the communication signal is a signal for vehicle-to-X communication,simultaneously transmitting and receiving by the transceiver, at least temporarily reflecting the communication signal as a reflection signal on the object in a signal propagation zone,receiving by the transceiver the reflection signal,determining phase information of the reflection signal or of the communication signal,determining a distance or a direction from the transceiver to the object from the phase information, wherein the phase information is in the form of differential phases of the reflection signal.

Abstract
The invention relates to a method for the position determination of objects (62, 707,84, 96) by means of communication signals, in which a transceiver capable of wireless communication transmits communication signals, the transceiver (51) being capable of simultaneous transmission and reception, and wherein the communication signals are at least partially reflected as reflection signals on at least one object (62, 707, 84, 96) in a signal propagation zone and the transceiver (51) receives the reflection signals. The method is characterized in that phase information of the reflection signals or communication signals are determined. The invention further relates to a corresponding device and to a use of the device.
