Automatic Interferogram Selection for SBAS-InSAR Based on Deep Convolutional Neural Networks [PDF]

Remote Sensing, 2021
<p>The small baseline subset of spaceborne interferometric synthetic aperture radar (SBAS-InSAR) technology has become a classical method for monitoring slow deformations through time series analysis with an accuracy in the centimeter or even millimeter range. Additionally, the process of calculating interferograms itself directly affects
