摘要:
对于相对论Doppler效应，纵向和横向运动都会产生Doppler频移；在非相对论Doppler效应中，运动速度远小于光速，纵向运动会产生Doppler频移，而横向运动不会产生频移。在现实中，宏观物体的运动速度不可能接近光速，故涉及到的都是非相对论的Doppler效应。本文理论分析表明，当横向运动引起等效的纵向位移或引起纵向传播的电磁波的相位变化时，横向运动也有可能产生频移。这能够成为一种新的检测原理，用于检测运动速度和目标外形等。
For relativistic Doppler Effect, both vertical and horizontal movements can generate Doppler frequency shift. The moving velocity is much less than the speed of light in the non-relativistic Doppler Effect, the vertical movement can generate Doppler frequency shift, while the horizontal movement cannot generate frequency shift. In reality, the movement velocity of macro-object is not close to the speed of light, so it is related to the Doppler Effect of non-relativity. Theoretical analysis in this paper shows that the horizontal movement will also generate frequency shift when the movement leads to equivalent vertical displacement or phase shift of the electromagnetic wave propagating in the vertical direction. This is able to be a novel detecting principle for detecting velocity, target shape, etc.
