英文摘要	Based on a simple starting model, Laplace-Fourier domain full waveform inversion (FWI) can recover a long wavelength velocity model from seismic data lacking low-frequency information. Although Laplace-Fourier domain FWI is equivalent to complex-frequency FWI, their implementation details are different from each other. Therefore, studies on complex-frequency FWI can lay a good foundation for comparison between the two and for developing a more efficient approach. In this paper, we first compare frequency domain inversion results of different frequency groups from an initial velocity model that increases linearly with depth (let's call it linearly increasing velocity model later). Then we combine these frequency groups with complex frequencies to do FWI and also compare the inversion results, tests on simple and complex velocity model both show that this complex-frequency-plus-frequency inversion style helps improve the inversion results.
