Typical \(3 \times 3\) covariance matrices (scaled to unit magnitude)
for urban, forest and pasture areas, taken from the simulation studies of
the authors' dissertation and thesis. They are handy to simulate PolSAR
data.
Usage
polsar_example_sigma(type = c("urban", "forest", "pasture"))
Arguments
- type
One of "urban", "forest" or "pasture".
Value
A complex Hermitian positive definite \(3 \times 3\) matrix.
Examples
polsar_example_sigma("forest")
