Abstract

The embodiment of the invention provides a correction method for the sea wave significant wave height of a satellite radar altimeter and a related device, and relates to the field of ocean detection.The method comprises the following steps: acquiring satellite radar altimeter data, wherein the satellite radar altimeter data comprises sea wave significant wave height, a backscattering coefficientand a backscattering coefficient standard deviation; and correcting the satellite radar altimeter data by using a pre-trained radar altimeter data correction model to obtain corrected sea wave significant wave height, wherein the radar altimeter data correction model is obtained by training based on the historical sea wave significant wave height, the historical backscattering coefficient, the historical backscattering coefficient standard deviation and the historical buoy observation sea wave significant wave height. The embodiment of the invention has the beneficial effects that the data ofthe satellite radar altimeter can be corrected, and the precision of the sea wave significant wave height in the data of the satellite radar altimeter is improved, so that the application value of thedata of the satellite radar altimeter is effectively improved.

Description

technical field [0001] The invention relates to the field of ocean detection, in particular to a method for correcting effective wave height of satellite radar altimeter and a related device. Background technique [0002] Waves are the most common and important natural phenomenon on the ocean surface, and they are also one of the most important factors affecting the safety of marine navigation, marine fisheries and other related marine activities. Therefore, accurate observation of ocean waves (that is, ocean wave observation) is of great significance to the life safety of personnel participating in marine activities and the development of ocean economy. At the same time, ocean waves will also have a non-negligible impact on the state of the atmosphere through the air-sea interaction, thereby affecting the weather and global climate. Therefore, accurate wave observation is extremely important for both academic research on the ocean and the atmosphere, as well as human sea-r...
