Abstract

The invention relates to an experimental device and method for microwave frequency attenuation and red-shift with propagation distance based on a Chen Shouyuan effect. The experimental device comprises a signal generating module, a microwave propagation channel and a signal detecting module; wherein the signal generating module is used for generating a microwave with set frequency and amplitude; the microwave reaches the signal detecting module through the microwave propagation channel; the signal detecting module observes the attenuation of the microwave frequency based on the propagation distance by measuring the frequency of the microwave; and the sound source position where the signal generating module generates the microwave, and the measuring point position of the microwave propagation channel and the signal detecting module remain relatively stationary.

Description

technical field [0001] The invention relates to the field of teaching and scientific research instruments, in particular to a microwave frequency attenuation and redshift experimental device and method based on the Chen Shouyuan effect. Background technique [0002] After decades of development, the theory and technology of microwave generation, propagation and reception have gradually matured and are mainly used in radar detection, satellite communication, mobile communication and other fields. In addition, it is widely used in industrial and agricultural production, scientific research, medicine, biology and people's life. At present, the reason for the change of microwave wavelength is mainly believed to be due to the Doppler effect, that is, the wavelength of the object radiates changes due to the relative motion of the wave source and the observer, or the wavelength changes caused by the movement of the medium. The existing teaching platform is very mature for observin...
