Claim Text:
1. A method for communication signal-based position determination of objects in road traffic, comprising the steps of: transmitting wirelessly at least one data-transporting communication signal by at least one sender, wherein the at least one communication signal is reflected at least proportionally as a reflection signal by at least one object, receiving the at least one communication signal and the reflection signal by a receiver, and wherein the receiver determines a location of the at least one sender, determining a propagation time difference between the communication signal and the reflection signal by the receiver and a location of the object by the receiver, determining at least one Doppler frequency by mixing the at least one communication signal with an associated one of the reflection signal, the receiver, as a result of temporal observation of a change in the Doppler frequency, assigning thereto a relative-speed-dependent distance curve, the profile of the curve containing the position of at least one of the objects.
