Abstract

LA INVENCION SE REFIERE A UN METODO DE DETERMINAR ELECTROMAGNETICAMENTE LAS SITUACIONES DE CUERPOS ELECTRICAMENTE CONDUCTORES DEBAJO DE LA SUPERFICIE DEL SUELO, EN LA QUE SE GENERA UN PRIMER CAMPO ELECTROMAGNETICO CON LA AYUDA DE UN BUCLE A TRAVES DEL CUAL SE PASA UNA CORRIENTE ALTERNA SINUSOIDAL. EL BUCLE SE COLOCA EN O POR ENCIMA DEL NIVEL DEL SUELO DEBAJO DEL CUAL SE DETERMINARA LA UBICACION DE CUERPOS CONDUCTORES. EN LOS CUERPOS CONDUCTORES HAY CORRIENTES GENERADAS QUE A SU VEZ GENERAN UN CAMPO ELECTROMAGNETICO SECUNDARIO, EN EL QUE LOS VALORES DE LA AMPLITUD Y FASE DEL COMPONENTE ELECTROMAGNETICO DEL ASI FORMADO CAMPO ELECTROMAGNETICO TOTAL SE MIDEN EN TRES DIRECCIONES LINEALES INDEPENDIENTES CON LA AYUDA DE BOBINAS MONTADAS EN UN AGUJERO QUE SE EXTIENDE HACIA ABAJO EN EL SUELO DENTRO DE LA ZONA DE PROPAGACION DEL CAMPO PRINCIPAL. LOS VALORES MEDIDOS SE TRANSMITEN POR UNA LINEA DE TRANSMISION A UN RECEPTOR, YA QUE TAMBIEN SON LOS VALORES PARA DETERMINAR LA FASE DEL CAMPO PRINCIPAL, DEMANERA TAL QUE PERMITAN QUE SE CALCULE LA DIFERENCIA DE FASE ENTRE EL CAMPO PRINCIPAL Y EL CAMPO TOTAL. ESTA DIFERENCIA SE UTILIZA PARA DETERMINAR LOS TRES COMPONENTES REALES Y LOS TRES IMAGINARIOS DEL CAMPO SECUNDARIO, UTILIZANDOSE A SU VEZ ESTOS COMPONENTES PARA DETERMINAR LA LOCALIZACION DE LOS CUERPOS CONDUCTORES. LA INVENCION SE CARACTERIZA EN QUE LOS VALORES DE LA FASE DEL CAMPO PRINCIPAL SE MIDEN CONTINUAMENTE POR AL MENOS UNA BOBINA DE REFERENCIA COLOCADA FUERA DE LA SONDA, YA SEA POR ENCIMA O DEBAJO DE LA SUPERFICIE DEL SUELO, DENTRO DE LA ZONA DE PROPAGACION DEL CAMPO PRINCIPAL. LA BOBINA DE REFERENCIA SE ORIENTA DE TAL MANERA QUE RECIBA AL MENOS UN COMPONENTE DEL CAMPO MAGNETICO Y LAS SEÑALES OBTENIDAS DE LA BOBINA DE REFERENCIA, O LOS RESULTADOS DE LAS SEÑALES PROCESADAS, SE TRANSMITAN AL RECEPTOR EN UNA LINEA DE TRANSMISION.
