STATISTICAL DISTRIBUTION OF DETERMINANT OF POLARIMETRIC COVARIANCE MATRIX

摘要

This paper examines the use of standardised generalised variance for statistical modelling of forest clutter in ALOS PALSAR multilook L-band dual-polarisation (HH and HV) data. Its probability density functions (PDFs) under homogeneous model and texture model were obtained, where the PDFs can be expressed in terms of Meijer G-function. From the modelling results, the texture model was found to provide a better fitting compared with the homogeneous model.
