Reference Materials

Most of the materials I use comes from these references:

• gmtSAR documentation - look through appendices! gmtSAR itself
• Synthetic Aperture Radar Interferometry Rosen et al., 2000, Proc. IEEE.
• InSAR Geodesy Simons and Rosen, 2007, Treatise of Geophysics

Phase unwrapping:

• Satellite radar interferometry: Two-dimensional phase unwrapping Goldstein et al., 1988, Radio Science.
• Synthetic Aperture Radar Interferometry Rosen et al., 2000, Proc. IEEE.
• Two-dimensional phase unwrapping with use of statistical models for cost functions in nonlinear optimization Chen and Zebker, 2001, J. Opt. Soc. Am.
• Phase unwrapping in three dimensions with applications to InSAR time series Hooper and Zebker, 2007, J. Opt. Soc. Am.
