Method for calibrating shallow-sea double-sensor data effective wave energy through employing seabed refracted wave

The invention proposes a method for calibrating shallow-sea double-sensor data effective wave energy through employing a seabed refracted wave. The method comprises the steps: selecting nearest water sensor or land sensor data, and measuring the linear speed of a first-motion wave; enabling the first-motion wave to be divided into a direct wave and the seabed refracted wave according to the linear speed of the first-motion wave; respectively carrying out the trace gathering of the water sensor and land sensor data in a detection point domain, carrying out the trace gathering of each detection point, and reading the amplitude limit value of a segment where the first-motion wave is a refracted wave; comparing the amplitude limit values of corresponding traces of the water and land detection points at the same position, obtaining a plurality of energy calibration factors, eliminating outliers, and solving a mean value which is the energy calibration factor of the water and land sensors at the position. The method is simple, just needs to compare the energy of the seabed refracted waves and solve the mean value, and is very easy to implement. The method is used for calibrating the energy of the seabed refracted wave, and the energy of the seabed refracted wave does not contain singing interference, wherein the random noises, compared with the energy of the refracted wave, can be neglected. Therefore, the accuracy is greatly improved.
