Abstract

CALIBRAÇÃO DE ANTENA EM UMA FERRAMENTA DE PERFILAGEM. Trata-se de um método para calibrar uma ferramenta de medição eletromagnética que inclui implantar um circuito de teste em torno de uma primeira antena na ferramenta de medição eletromagnética e acoplar eletromagneticamente o circuito de teste e a primeira antena e medir uma primeira tensão. O circuito de teste é então implantado em torno de uma segunda antena na ferramenta de medição eletromagnética e são acoplados eletromagneticamente o circuito de teste e a segunda antena, e uma segunda tensão é medida. É computada uma razão entre a primeira tensão e as segundas tensões, que pode ser usada para calibrar a primeira antena em relação à segunda antena.
