AI Technical Summary
In complex terrain areas, InSAR surface deformation monitoring is not accurate enough and the results are not reliable. This is mainly because geometric distortions such as overlapping and shadows caused by complex terrain cause radar echo signals to be interfered with by factors such as terrain orientation and surface roughness. Traditional phase unwrapping algorithms are difficult to accurately recover the true phase.
By acquiring multi-source monitoring data, including multi-temporal synthetic aperture radar imagery and digital elevation model data, sub-regions are divided, the degree of terrain interference is quantified, a comprehensive terrain interference index is determined, and unwrapping processing is optimized based on phase quality weights to suppress phase error propagation.
It significantly improves the accuracy and reliability of deformation inversion results in complex terrain environments, effectively suppresses the propagation and accumulation of phase errors in space, and enhances monitoring accuracy and reliability.
