The New Form of G Distribution for Single-look PolSAR Data

Inhalt:
When High Resolution (HR) is required, single-look processing of SAR images may be desirable. The multi-look G distribution has been known to fit homogeneous to extremely heterogeneous data accurately. However, it does not reduce to single-look form for PolSAR data. To eliminate this limitation, the new single-look polarimetric G distribution has been proposed, which has single-look Kp and Gp⁰ distributions as its two special cases. The significance of this distribution becomes evident as it fits X- & S-band sub-meter resolution (˜ 1m(exp2)) PolSAR data better than, and X-band decameter resolution (˜ 10m²) PolSAR data as good as, the Gp⁰ & Kp distributions
