wradlib.dp.DpMethods.unfold_phi_vulpiani#
- DpMethods.unfold_phi_vulpiani(**kwargs)[source]#
Alternative phase unfolding which completely relies on \(K_{DP}\).
This unfolding should be used in oder to iteratively reconstruct \(Phi_{DP}\) and \(K_{DP}\) (see [Vulpiani et al., 2012]).
Note
\(Phi_{DP}\) is assumed to be in the interval [-180, 180] degree. From experience the window for calculation of \(K_{DP}\) should not be too large to catch possible phase wraps.
