IONOSPHERIC MOTION AND FREQUENCY VARIATION OF RADIO WAVE

In this paper, Doppler shift of radio wave echoes reflected from a spatially slowly, varying ionosphere is discussed. It shows that a moving reflection surface does not necessarily imply a moving medium. The idea which shows the height of equivalent reflection mirror is not necessarily in deviation region of waves is also discussed. Amethod to obtain the isodensity surface velocity profile from the inversion of ordinary and extraordinary wave Doppler shift is suggested.
