Embodiment 3

[0210] Based on the Chen Shouyuan effect, the distance measurement method of acoustic wave redshift in water is based on the fact that when the redshift of acoustic wave in water is small, it has an approximately linear relationship with the distance, or the actual distance is converted by measuring the redshift of the sound wave returned to the water. When the redshift is large, the redshift has an exponential relationship with the distance. According to this relationship, the distance of the target object can be calculated from the redshift measurement of the acoustic wave in water. The measurement method measures the distance with the relationship between the sound wave in water and the propagation distance and wavelength change (red shift), and corrects the measurement results with the relationship between the wave source power and the red shift of the sound wave in water, and the wave source frequency and the red shift of the sound wave in water.

Abstract

The invention discloses a water wave redshift measuring system and method based on a Chen Shouyuan effect. The system is suitable for the condition that a water wave transmission medium is free from longitudinal movement. The water wave redshift measuring system based on the Chen Shouyuan effect comprises a sound wave source, at least two transverse wave probes and a controller, wherein the amplitude, transmission frequency and phase size of the sound wave source are preset; the sound wave source is arranged at a preset geographic position in a selected water area; the at least two transverse wave probes are arranged on the circumference of different concentric circles taking the sound wave source as a circle center; the transverse wave probes are provided with unique codes according to the positions of the transverse wave probes; the transverse wave probes are used for acquiring transverse wave signals which are transmitted to the positions at which the transverse wave probes are positioned and coding information of the transverse wave probes, and transmitting the transverse wave signals and the coding information to the controller; the controller is used for resolving the received signals to obtain the amplitudes, the transmission frequencies and the phase size information of transverse waves collected by the transverse wave probes, so that a water wave redshift value can be obtained.

Description

technical field [0001] The invention belongs to the field of redshift measurement, in particular to a water wave redshift measurement system and method based on the Chen Shouyuan effect. Background technique [0002] In the field of physics and astronomy, redshift refers to the phenomenon that the wavelength of electromagnetic radiation of an object increases due to some reason. In the visible light band, it is manifested that the spectral line of the spectrum moves a certain distance toward the red end, that is, the wavelength becomes longer. Current theory explains the Doppler effect as the distance between the light source and the observer increases. The phenomenon of redshift is currently mostly used in the prediction of the movement and laws of celestial bodies. [0003] Chen Shouyuan effect: that is, during the propagation of water waves, the wave energy intensity decreases due to factors such as wave energy loss and diffusion. Since frequency is a factor of wave ener...
