SAR remote sensing has been expected as an efficient rice crop monitoring tool due to its flexible operability with wide swath. Though many researchers have intensively analysed the backscatter, there still exist non-negligible mysteries to extract physical parameters. To solve the problems, it is essential to conduct theoretical characterization of experimentally obtained radar backscatter from rice...
SAR Tomography, or TomoSAR, is one of the powerful SAR data analysis tool with multi-baseline data set, especially for height estimation of scattering centers. On the other hand, PolSAR, or Polarimetric SAR, is also powerful tool for scattering characteristic discrimination of terrain. Several PolSAR analyses have applied to the TomoSAR. However the application of model-based PolSAR scattering power...
We presented two target decomposition methods for polarimetric interferometric SAR (PolInSAR) images parallel to the eigen-decomposition and scattering power decomposition for polarimetric SAR (PolSAR) images. For both cases, we showed the importance of PolInSAR coherence estimation, and in particular, the newly proposed best normal matrix approximation algorithm in successful decomposition of PolInSAR...
This paper proposes a simple algorithm for detecting largely-oriented man-made object by using angular index β, in addition to the conventional angular index a. The angular indices are derived by the eigenvalues/eigenvectors analysis to the rotated coherency matrix of fully polarimetric SAR data. Here the orientation angle compensation (OAC) is carried out to the coherency matrix before doing the...
