Abstract
For ambient noises reconstruction, crosscorrelation and deconvolution seismic interferometry are two feasible methods. These two methods are often conducted in frequency domain. To reduce the errors caused by signal processing and reconstruct better relative amplitude, we propose a reconstruction method based on multi-tapers spectral estimation. We adopt multiple sinusoidal tapers to avoid frequency leakage. Based on conventional crosscorrelation and deconvolution method, we present the representations of multiple sinusoidal tapers reconstruction method. In the numerical example, we find that the reconstruction results after multiple sinusoidal tapers processing present more deep information, and multiple sinusoidal tapers deconvolution method gives the best relative amplitudes.
