摘要
多普勒效应是指当波源或观测者相对于介质发生运动时 ,观测者所观测到的频率与波源实际发出的频率有所不同 ,这种现象也称为多普勒频移 .在现代技术中多普勒频移有着广泛的应用 .介绍了现代技术中多普勒效应的几个应用实例 。
Doppler effect means the different phenomeon between the rate of the observation and the wave source which is achieved by the observer when he does certain movement oppsite to the meterial. It is also called Doppler frequency motion. Which is widely used in modern technology.This article is concerned with the application of Doppler effect to modern technology, and its theoretical analysis and researon.
