A method to extract the polarization of $\Omega$ hyperons produced via thestrong interaction is presented. Assuming they are spin 3/2 particles, thecorresponding spin density matrix can be written in terms of seven non-zeropolarization parameters, all retrievable from the angular distribution of thedecay products. Moreover by considering the full decay chain $\Omega\rightarrow\Lambda K\rightarrow p\pi K$ the magnitude of the asymmetry parameters$\beta_\Omega$ and $\gamma_\Omega$ can be obtained. This method, applied hereto the specific $\Omega$ case, can be generalized to any weakly decayinghyperon and is perfectly suited for the PANDA experiment wherehyperon-antihyperon pairs will be copiously produced in proton-antiprotoncollisions. The aim is to take a step forward towards the understanding of themechanism that reigns strangeness production in these processes.
