In this paper, the expression of Wigner operator in the coherent state is derived using the IWOP technology. The Wigner function of a kind of special single-mode squeezed state is calculated. When the rotation parameter value changes, the numerical calculations show that the Wigner function in the phase space possesses a rotation displacement feature.
