But for land- or marine-streamer acquisition geometry this approach faces the challenge of erroneous misfit due to the mismatch between the limited number of live traces\/shot recorded in the field and the pervasive number of traces generated by the finite-difference modeling method. To tackle this mismatch problem, a key enabling frequency selection strategy is described: At each FWI iteration, we assign a unique frequency band to each shot gather, so that the spectral overlap among those shots-and therefore their crosstallk-is zero. Consequently, each receiver can unambiguously identify and then discount the superfluous sources-those that are not associated with the receiver in the streamer acquisition. This strategy allows significant speedup of FWI.","brand":"LAP LAMBERT Academic Publishing","offers":[{"title":"Default Title","offer_id":53366627598678,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9783330073098_1.jpg?v=1778855454","url":"https:\/\/www.momoxbooks.com\/products\/huang-yunsong-full-waveform-inversion-with-multisource-frequency-selection-9783330073098","provider":"momoxbooks","version":"1.0","type":"link"}
