Abstract	Summary In this paper, we compare one-way wave propagator and full-wave propagator such as finite difference (FD) method i n the evaluation of illumination and acquisition dip response (ADR) maps. For the case of 2D SEG/EAGE salt model, the illumination and ADR maps by the one-way method and the FD method have similar general distributions in space and angle domain. However, some difference exists in absolut e values, especially for the subsalt area. This is due to the strong effects of transmission loss caused by salt boundary scat tering, reflection and defocusing. The difference in wide-angle amplitude behavior is also noticeable. Therefore, in most cases illumination analysis calculated by one-way wave propagators can provide reliable evaluation.
