Research on Large Volume Airgun Source Signal Reception in Hutubi, Xinjiang Using Seismic Network Data-中国Betway体育网页登陆

摘要 WeuseddatafromtheXinjiangDigitalSeismicNetworkandPSD(PowerSpectralDensity)methodtoperformnoiselevelassessmentforsixstations.Wecalculatedthemedianofthepowerspectraldensitytoevaluatethenoiselevelofdifferentstations.Afterthecomparisonofthepowerspectraldensityofdifferentstationsandtheairgunsignalrecognition,wefoundthatnoiselevelofstationswithrecognizableairgunsourcesignalsislowerthanthatofstationswithoutrecognizablesignals.Thelargestdifferenceofthepowerspectraldensityis40dB,andthesmallestis15dB.Finally,wefoundthatthefailuretorecognizethesignalofairgunsourcesatsomestationsisduetothenoiselevel.
