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 ).
$$Phi_{DP}$$ 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.
