Abstract

"APARELHOS PARA REMOVER RUìDO DE UM CANAL DE SINAL EM UM SISTEMA DE TELEMETRIA ELETROMAGNéTICO DE FURO DE SONDAGEM E PARA RECEBER DADOS TRANSMITIDOS POR UM TRANSMISSOR ELETROMAGNéTICO EM UM FURO DE SONDAGEM, E, MéTODOS PARA REMOVER RUìDO DE UM SINAL RECEBIDO POR UM RECEPTOR E PARA PROVER UM CANAL DE RUìDO ELETROMAGNéTICO PARA UM SISTEMA DE TELEMETRIA DE FURO DE SONDAGEM ELETROMAGNéTICO". Um sistema de telemetria de furo de sondagem eletromagnético que fornece melhor relação sinal/ruído está mostrado na figura 1. Filtros adaptativos (28) usam canais de ruido como referências para remover ruído do canal de sinal. Sensores melhorados (40) fornecem canais de ruído com baixo teor de sinal. Os sensores de movimento (42) são protegidos contra sinais eletromagnéticos para prevenir detecção do sinal de telemetria.
