San Francisco PolSAR image (150 x 150 pixels)

A \(150 \times 150\) crop of the fully polarimetric L-band AIRSAR image of the San Francisco Bay area (nominal 4 looks), used in the dissertation and thesis of J. A. Ferreira. The scene contains ocean, vegetation (forest/park) and urban areas; see SanFrancisco150_gt.

Usage

SanFrancisco150

Format

A complex array of dimension 150 x 150 x 6. For each pixel the six layers are the distinct entries of the \(3 \times 3\) Hermitian covariance matrix: \(|S_{HH}|^2\), \(|S_{HV}|^2\), \(|S_{VV}|^2\) (real intensities), \(S_{HH}S_{HV}^*\), \(S_{HH}S_{VV}^*\) and \(S_{HV}S_{VV}^*\) (complex products).
