Problems solved by technology

The traditional wave measurement system adopts fixed-point, single-point and single-line-of-sight observations. It can only observe waves in a certain area, a certain position or a certain direction. The observation dimension is single, and generally adopts indirect measurement methods (not directly The measured value of the ocean wave), it is necessary to invert the wave height, wave velocity and wave direction and other parameters of the ocean wave through other elements and use th

Abstract

The invention discloses a sea wave height detection method, device and apparatus and a storage medium. The sea wave height detection method comprises the following steps of: receiving a first echo signal returned by an emission source from a to-be-detected point at a first position, and receiving a second echo signal returned by the emission source from the to-be-detected point at a second position; determining a phase difference between the first echo signal and the second echo signal; and determining the height of the to-be-measured point according to the phase difference, the distance between the second position and the to-be-measured point and a first position parameter. The problem that sea wave height measurement accuracy is poor is solved; the accuracy and stability of sea wave height measurement are improved; and the use efficiency of ocean remote sensing measurement equipment is improved.

Description

technical field [0001] The embodiments of the present invention relate to a detection technology of sea wave height, and in particular to a detection method, device, equipment and storage medium of sea wave height. Background technique [0002] Waves are key elements of the marine environment that affect the navigation safety and combat effectiveness of surface ships. The traditional wave measurement system adopts fixed-point, single-point and single-line-of-sight observations. It can only observe waves in a certain area, a certain position or a certain direction. The observation dimension is single, and generally adopts indirect measurement methods (not directly The measured value of the ocean wave), it is necessary to use other elements and use their corresponding relationship to invert parameters such as wave height, wave velocity and wave direction of the ocean wave, and there are many uncertain factors in the corresponding relationship between elements. In addition, wa...
