Firstly, short-time Fourier transform is introduced as one of time-frequency methods, that has more capability than Fourier transform and gives us sensible feature of signal. Optimal window-length computing methods, such as optimization method and chirp rate method in order to enhancing resolution, have been investigated, analytically. Output results and their comparisons endorse e¿ective role of window-length as an important parameter. Like automated first-break picking methods that use instantaneous attributes, we utilize short-time Fourier transform in order to extraction of a local attribute for automatic picking of arrival time. Furthermore, using this tool, we can calculate instantaneous traveltime that help us to identify seismic events in a trace. This procedure leads to detection of reflectors and seismic horizons in the prestack and poststack seismic gathers and sections.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202079945\"\u003e\u003ch3\u003eAutomatic First-break Picking and Determination of Seismic Events Traveltime\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202079945","offer_id":39448502304861,"sku":"9786202079945","price":35.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/9f3b50a7-f6db-49e0-9663-2f38440cdc15.jpg?v=1773475377","url":"https:\/\/shop.autorenwelt.de\/products\/high-resolution-time-frequency-distribution-automatic-first-break-picking-and-determination-of-seismic-events-traveltime-von-mohammad-bejvani","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
