Problems solved by technology

Therefore, this method is suitable for fixed land-based measurement equipment, but in the shipboard application scenario, when the ship sails to an unknown sea area, the effective wave height cannot be correctly inverted without the calibration data of the corresponding sea area

Abstract

The invention discloses a sea wave height calculation method, and the method comprises the steps: adjusting the pulse width of a radar to be minimum, collecting a first image sequence, and recording afirst true course angle sequence and a first longitude and latitude coordinate information sequence of a ship; selecting an image inversion area, and performing inversion area motion compensation; carrying out sea wave information inversion to acquire the main wave length of sea waves; adjusting the pulse width of the radar to enable the resolution of the radar to be equal to the main wave lengthof sea waves, collecting a second image sequence, and recording a second true course angle sequence and a second longitude and latitude coordinate information sequence of the ship; selecting an imageinversion area, and performing inversion area motion compensation; calculating the sea surface average radar sectional area of the inversion area; and calculating the effective wave height of the seawave. The method has the beneficial effect that the effective wave height can be inversed in all sea areas only by one-time calibration.

Description

technical field [0001] The invention belongs to the technical field of ocean wave remote sensing, and in particular relates to an ocean wave height calculation method, a terminal and a measurement system. Background technique [0002] The microwave radar remote sensing test method is a new wave telemetry method that has emerged in the world for more than 20 years. It has the advantages of low cost, all-day, all-weather, small platform size, and can sail with ships. [0003] The technical scheme of using microwave radar to remotely measure ocean waves is briefly described as follows: microwave radar collects a set of radar image sequences in chronological order, performs three-dimensional Fourier transform to obtain image spectrum, and then converts the image spectrum into wave number spectrum through modulation transfer function, and then Estimate the current velocity, wave direction, and wavelength data of ocean waves. For the estimation of the effective wave height of se...
