With the growing demand for wireless communication systems, wireless concepts for the data exchange in time variant scenarios become more and more interesting. In order to describe and thus assess the mobile radio channels in such scenarios, simulations are required. The main aspect is the time-variance of the channel impulse response and the modelling of large scenarios. This paper discusses the demands for models to describe the radio channel in time variant environments and presents an appropriate ray tracing approach. A new concept is introduced to substitute polygonal objects by their radar cross section (RCS) data. The performance of the ray tracing algorithm is demonstrated by a comparison from predictions to several measurement campaigns.
