电磁波既有纵向多普勒效应,也存在横向多普勒效应,一般电动力学教科书中对纵向多普勒效应多有讨论,易于理解且无争议,但对横向多普勒效应则少见详细、正确的报道。本文基于普遍的电磁波多普勒效应表达式,结合光行差公式,对电磁波多普勒效应进行了全面的辨析,指出对横向多普勒效应,波源的运动与探测器的运动是等价的,无论源静止、接收器运动还是源运动、接收器静止,横向多普勒效应都应只存在红移,不可能出现蓝移,并对横向多普勒效应蓝移错误的原因进行了分析。
電磁波既有縱嚮多普勒效應,也存在橫嚮多普勒效應,一般電動力學教科書中對縱嚮多普勒效應多有討論,易于理解且無爭議,但對橫嚮多普勒效應則少見詳細、正確的報道。本文基于普遍的電磁波多普勒效應錶達式,結閤光行差公式,對電磁波多普勒效應進行瞭全麵的辨析,指齣對橫嚮多普勒效應,波源的運動與探測器的運動是等價的,無論源靜止、接收器運動還是源運動、接收器靜止,橫嚮多普勒效應都應隻存在紅移,不可能齣現藍移,併對橫嚮多普勒效應藍移錯誤的原因進行瞭分析。

The electromagnetic wave not only has longitudinal Doppler effect,but also has transverse Doppler effect.Longitudinal Doppler effect is discussed in many electrodynamics textbooks,which is easy to understand and has no dispute about it.But there is little correct and detailed report about transverse Doppler effect.Based on the ordinary formula of Doppler effect for electromagnetic wave,and integrated with aberration formula,a thorough analysis and discussion on Doppler effect for electromagnetic wave is given in this paper.It is pointed out that the movement of the source and the receiver are equivalent in electromagnetic wave Doppler effect.Transverse Doppler effect only has red shift no matter when the source moves or the receiver moves.Blue shift in transverse Doppler effect is impossible,and the reason of that is explained.
