Sea ice concentration retrieval method and device based on brightness temperature data and electronic equipment

Abstract

This invention discloses a method, apparatus, and electronic device for sea ice concentration inversion based on brightness temperature data, belonging to the field of sea ice concentration inversion technology. The method includes: inputting brightness temperature observation vectors into multiple scale branches; extracting features from the brightness temperature observation vectors at different scales to obtain multiple scale features; generating multiple feature factors from the brightness temperature observation vectors through multiple sets of low-dimensional mappings; and performing element-wise multiplication on the multiple feature factors to obtain cross features; concatenating the multiple scale features and the cross features to obtain an initial fused feature vector; performing dense residual encoding on the initial fused feature vector through an intermediate layer to obtain decoded features; inputting the decoded features into an output layer; and mapping the decoded features to a one-dimensional sea ice concentration space to obtain a sea ice concentration scalar. This method can improve the accuracy of sea ice concentration inversion results.
