Integrating Gross Error Identification with Deep Learning for InSAR Topography-Dependent Delay Correction: A Case Study of the Baihetan Hydropower Station Area

Remote Sensing
Tropospheric delay poses a major limitation to high-precision InSAR observations, particularly in high mountain and canyon regions. To address this issue, this study proposes a combined model (EiMLP) that integrates gross error identification with a ...
