The complex ray expansion is a simple approach for target scattering field computation, whose effectiveness depends on the systematic investigation of its error. In this paper, plane wave spectral integral is used as a standard reference and the distance defined by norm in L2 space is introduced as the error function for comparison between the two methods, and then the error characteristics of complex ray expansion appoach for target scattering field computation are obtained. The way to decrease the error and the application range of the complex ray expansion method are also obtained.
