Change detection in quad and dual pol, single- and bi-frequency SAR data | Allan Aasbjerg Nielsen, Knut Conradsen, Henning Skriver
| Abstract | When the covariance matrix representation is used for multi-look polarimetric synthetic aperture radar (SAR) data, the complex Wishart distribution applies. Based on this distribution a likelihood ratio test statistic for equality of two complex variance-covariance matrices and an associated p-value are given. In a case study airborne EMISAR C- and L-band SAR images covering agricultural fields and wooded areas near Foulum, Denmark, are used in single- and bi-frequency, bi-temporal change detection with full and dual polarimetry data. | Type | Conference paper [With referee] | Conference | SPIE Remote Sensing | Year | 2015 Month September Vol. 9643 Ed.
