This invention relates to the field of atmospheric phase compensation technology and discloses a GB-InSAR atmospheric phase compensation method based on LSTM. Because the atmospheric delay coefficients of electromagnetic wave propagation may vary in each azimuth, the atmosphere has a spatially variable effect on radar data monitoring. Therefore, conventional atmospheric phase compensation methods are no longer applicable. This paper proposes an LSTM-based atmospheric phase compensation method. First, the correlation coefficient and phase average value of the PS points are calculated to construct an evaluation factor. The evaluation factor is selected and input into the LSTM to obtain the temporal phase variation characteristics of the PS points. A classification model is constructed and all PS points are classified using the K-means method. The class with the smallest standard deviation is selected as the stable point to verify the reliability of the model and obtain a suitable classification model. The classification model is then used to classify all PS points and select stable PS points. Finally, Lowess interpolation fitting is performed based on the stable PS points to compensate for the atmospheric phase of the PS points. This method is suitable for scenarios with complex weather conditions.
