Abstract

SISTEMA DE PROSPECçãO ELETROMAGNéTICA, SISTEMA RECEPTOR PARA UM SISTEMA DE PROSPECçãO ELETROMAGNéTICA E MéTODO PARA COLETAR DADOS EM UM SISTEMA DE PROSPECçãO ELETROMAGNéTICA. Um sistema receptor (18) para um sistema de prospecção eletromagnética é divulgado. O sistema de prospecção eletromagnética compreende um transmissor para transmitir um campo eletromagnético primário de modo a gerar um campo eletromagnético secundário a partir de um terreno que está sendo prospectado, o campo eletromagnético secundário tendo um perfil de domínio de tempo de deterioração, transiente. O sistema receptor (18) compreende primeiro e segundo sensores (20, 22) para detectar o campo eletromagnético secundário, sendo que o segundo sensor (22) é menos sensível que o primeiro sensor (20) de modo a detectar o campo eletromagnético secundário durante um primeiro período de tempo, com o primeiro sensor (20) sendo usado para detectar o campo eletromagnético secundário após o primeiro período de tempo. Tipicamente, cada sensor (20, 22) compreende três magnetómetros SQUID ortogonais, com o segundo sensor (22) sendo aproximadamente 10 vezes menos sensível que o primeiro sensor (20)
