Doppler-like frequency shifts of electromagnetic waves


Cs. Ferencz and Gy. Tarcsai

ABSTRACT

It was shown by Wolf and Foley (1989) that correlated space-time fluctuations of scattering media can produce Doppler-like frequency shifts. In support of these findings the paper summarizes earlier results in this field. The anomalous frequency shifts observed in terrestrial troposcatter and solar radio occultational measurements, and in the Fraunhofer-lines at the extreme solar limb, could be explained well by simple heuristic models including moving inhomogeneous scattering media.
