We develop a method to evaluate the resolution of seismic images using a wave-equation-based operator. The one-way wave-equation-based propagator is used to extrapolate the wavefields from both the source and receivers to a target region. The plane wave analysis method is used to decompose the wavefields and calculate the wavenumber domain resolution function. The method can be applied to complex models without smoothing velocity. It can also handle irregular acquisition geometry and finite frequency band. The resulting resolution function can be used to estimate image quality or correct the image distortion caused by the uneven illumination.
