The routines provided in the link below compute the performance of 3-D surface deformation for simultaneous squinted acquisitions using the Hybrid Cramér-Rao Bound (HCRB). The IDL code implements the HCRB as presented in the following paper:
P. Prats-Iraola, P. Lopez-Dekker, F. De Zan, Yague-Martinez, M. Zonno, M. Rodriguez-Cassola, "Performance of 3-D Surface Deformation Estimation for Simultaneous Squinted SAR Acquisitions," IEEE Transactions on Geoscience and Remote Sensing, vol. 56, no. 4, April 2018.
In particular, the example provided in the code computes the plots for Figures 5 and 6 in the paper with the system parameters provided in Table II. The other plots can be easily obtained using the provided functions.
Please note that the software requires in addition the autocorrelation function assumed for the atmospheric boundary layer (ABL). The one used for the performance computation of the paper is provided in the ZIP file in the IDL SAV format.
Click on the following link to download the ZIP file including the IDL code and the autocorrelation function: multisquintSurfaceDeformationPerformance.zip.
This ZIP file includes the source code file “multisquintSurfaceDeformationPerformance.pro” and the autocorrelation function of the ABL in SAV format “ABLautoCorrelation.sav”.
