This paper examines multi-path propagation modeling in moderate and highly dynamic multi-path environments. An enhanced multipath model is proposed with emphasis on conversion from the multi-path Doppler shifts into their code delay shifts. Analytical derivation of the conversion mechanism is related to two simplified scenarios of aligned transmitter, reflector and receiver. The model is further applied to a set of processed IF samples to try to explain peculiarities of some of urban environment measurements, and of partially unresolved urban-canyon and aviation landing measurements performed by others.
