This article proposes the application of various alternative definitions of the multivariate coefficient of variation parameter in two domains: radar polarimetric time series and dynamic polarimetric speckle. In the first case, the focus is on detecting permanent scatterers or changes, while in the second case, it involves calculating activity images. Our study demonstrates that most of these parameters offer added value in terms of signal-to-noise ratio improvement and enhancing contrast in specific regions. Furthermore, the concept of polarimetric multivariate coefficient of variation proves to be closely related to the degree of polarization.
