In this poster we introduce a new model free polarimetric analysis method based on quaternion Fourier transform and we also present a method to reconstruct both gravitational-wave polarizations from the full network data. Interestingly, this formalism allows to formulate generic priors on the polarization that can guide the problem inversion. As an illustration we perform the polarimetric spectral analysis on precessing BBH signal and show that the precessional motion of the binary orbital plane can be tracked from the polarization time evolution.
