Abstract

resumo patente de invenção: "medição de nível de radar mfpw com aproximação de distância". a presente invenção refere-se a uma medição de nível que inclui uma aproximação de uma distância da superfície de um produto mantido em um tanque. a aproximação é determinada relacionando-se uma amplitude de um primeiro harmônico de um sinal de if com uma amplitude de um segundo harmônico do sinal de if. basicamente, cada harmônico representa uma faixa de distância dada. determinando-se a potência recebida em dois ou mais harmônicos, e correlacionando os mesmos um com o outro, a distância pode ser estimada. dependendo da modulação e de outros parâmetros, a dependência da distância pode ser muito diferente, e pode ser selecionada para se adequar à aplicação.
