In this talk we compare our non-stationary geometricstochastic channel model for vehicle-to-vehicle scatter channels with measurement data collected in a vehicle-to-vehicle measurement campaign. The measurements were conducted on a forest road near Munich at 5.2 GHz using a car mounted transmitter and receiver platform. The data is evaluated in terms of delay and Doppler frequency and then compared to a scaled version of the joint delay Doppler probability density function. The close agreement between the analytical and empirical data confirms the utility of our non-stationary geometric stochastic model.
