The multiples usually have wider illumination range and contain more information than the primary reflection, so instead of suppression, multiple imaging has attracted more and more attention nowadays. The traditional multiple imaging methods replace the source wavelet with recorded data and use the predicted multiples as the receiver record, however, the crosscorrelation of the unrelated events will introduce heavy crosstalk artifacts when using the conventional imaging condition which the primary migration methods used. In this paper, we propose to introduce the stereographic imaging condition to solve this problem, by adding a local slope constrain, this method can well suppress the crosstalk artifacts. In order to improve the computational efficiency, we adopt the one-way wave-equation migration method for multiple imaging in this paper. The numerical examples verify the feasibility and effectiveness of this method, better multiple imaging results are obtained in the numerical tests.
