多普勒效应对微波输电的影响

Influence of Doppler Effect on Microwave Power Transmission

从光行差的角度出发,在运动系中分别得出微波的纵向多普勒效应和横向多普勒效应的表达式,并讨论这两种多普勒效应因接收器运动速度、角度的变化对接收端微波频率产生的影响,为消除该影响,得到在波源处对发射频率的修正公式,并通过图像展示接收器的运动速度、角度与频率变化三者之间的关系,为波源与接收器相对运动的长距离微波输电提供一定参考.

From the point of view of optical aberration,the expressions of longitudinal Doppler effect and transverse Doppler effect of microwave are obtained in the motion system.The influences of these two Doppler effects on microwave frequency at the receiving end due to the change of receiver’s motion speed and angle are discussed comprehensively,and the correction formula of transmitting frequency at the wave source is obtained in order to eliminate the influence.The relationship among receiver’s motion speed,angle and frequency change is shown through images,which provides a reference for long-distance microwave transmission with relative motion between the wave source and the receiver.
