Abstract
Patente de Invenção: <B>"MéTODO DE ANáLISE DE SINAIS ADQUIRIDOS PARA LOCALIZAçãO AUTOMáTICA NELE DE PELO MENOS UM INSTANTE SIGNIFICATIVO"<D>. Método pretendido para uma análise automática de sinais adquiridos por um ou mais captadores de onda elástica ou acústica, de modo a localizar automaticamente neles, com alta precisão, pelo menos um instante significativo , tal como o tempo de primeira chegada em cada captador (t~ i~) e/ou o tempo final (t~ f~) desses sinais. O método essencialmente compreende a determinação do pseudoperíodo correspondente ao inverso da freq³ência dominante do espectro de freq³ência de cada sinal adquirido, a codificação de cada sinal adquirido, de modo a formar um sinal codificado binário com referência a um primeiro valor limite, que depende do sinal adquirido, a formação, para cada um deles, de um sinal integral pelo empilhamento do sinal codificado binário em uma janela deslizante, de modo a determinar um segundo valor limite, e o posicionamento do instante significativo buscado (t~,i~ t~ f~) em cada sinal adquirido, com referência a um instante em que o sinal integral correspondente atinge este segundo valor limite. O método é auto-adaptativo, porque ele usa parâmetros (notadamente os valores limite) que dependem das características dos sinais recebidos. Ele pode ser aplicado notadamente para monitoração sísmica (ativa ou passiva) de reservatórios subterrâneos, no campo da acústica em geral, em sonares, etc.
