Abstract

The invention discloses a super-resolution reestablishment method for a microwave remote sensing image based on an SRCNN (Super-Resolution Convolutional Neural Network) and belongs to the technology of microwave remote sensing and detection. The method comprises the steps of firstly simulating a microwave remote sensing flow, and forwardly producing a high-resolution microwave remote sensing imageTB and a low-resolution microwave remote sensing image TA to form a data set; then preprocessing the data set to generate an SRCNN training set; constructing a five-layer depth convolutional neural network based on the SRCNN training set; and finally inputting the to-be-processed low-resolution microwave remote sensing image to the constructed five-layer depth convolutional neural network, wherein the output of a fourth-layer of the depth convolutional neural network is the reestablished high-resolution microwave remote sensing image. With the super-resolution reestablishment method for the microwave remote sensing image based on the SRCNN, the calculation complexity in reestablishment can be effectively reduced, an accurate antenna pattern is not needed, the method is a novel microwave remote sensing image reestablishment method, and a brightness temperature image of an original scene can be efficiently reestablished in real time.
