As the result of the particular medium properties of ionospheric Alfvén resonator（IAR）, high frequency incident waves may manifest the Doppler effect different from that in free space. To start with the specially extended Doppler formula for IAR, we discuss the causes for the Doppler shifts and calculate their values. The results show that in IAR the Doppler effect is mainly due to the motion of high-speed flyer and drifting electrons, and the frequency shift from the phase variation by reflected waves can be neglected when the frequency of HF wave incident on the ionosphere is high enough. 电离层阿尔芬谐振器 高频波 Doppler效应 ionospheric Alfvén resonator heating HF waves Doppler effect P352.3 国家自然科学基金资助项目 （ 4 990 40 10 ） 2003-03-01 2021-04-01 3
