Three-dimensional surface deformation mapping by convensional interferometry and multiple aperture interferometry
H.-S. Jung, Z. Lu, C.-W. Lee
2011, Conference Paper, 2011 3rd International Asia-Pacific Conference on Synthetic Aperture Radar, APSAR 2011
Interferometric synthetic aperture radar (InSAR) technique has been successfully used for mapping surface deformations [1-2], but it has been normally limited to a measurement along the radar line-of-sight (LOS) direction. For this reason, it is impossible to determine the north (N-S) component of surface deformation because of using data from...
