Abstract

"PROCESSO DE REDUçãO DO RUìDO HARMÈNICO EM UM SINAL VIBROSSìSMICO REGISTRADO POR UM CAPTOR". Processo de redução do ruído harmónico em um sinal vibrossísmico registrado por um captor, este sinal vibrossísmico correspondendo a uma seq³ência vibratória dada emitida por pelo menos uma fonte e propagada em um subsolo no qual ele é refletido, caracterizado pelas etapas de acordo com as quais: a) correlaciona-se o sinal vibrossísmico ou uma parte deste com um sinal que corresponde ao componente fundamental da seq³ência de vibrações emitida pela fonte b) seleciona-se no sinal correlacionado uma parte que corresponde à energia do componente fundamental do sinal vibrossísmico e aplica-se à parte selecionada, um operador de estimação do componente harmónico do dito sinal correlacionado c) deduz-se dele uma estimação do ruído harmónico do sinal vibrossísmico e se subtrai esta estimação do dito sinal.
