The Wigner function formalism has been applied to the analysis of elastic scattering processes. The new element of known formalism is the choice of the phase space on which the Wigner function is defined. This phase space is 4-dimensional space of canonically conjugate variables - the transverse momentum of scattered particle and the projection of the vector of the closest approach of particles in the plane which is perpendicular to the momentum of initial particle. The exact expression for the mean value of the scattered particles production area radius through a scattering amplitude has been obtained.
