# 基于横向运动的频移分析—对一种新检测原理的探讨Analysis of Frequency Shift Based on Horizontal Movement—Discussion on a Novel Detecting Principle

Abstract: 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.
