Abstract

FORMA DE ONDA TRANSMISSORA DE ESPECTRO LOGARìTMICO PARA MEDIçãO ELETROMAGNéTICA DE FONTE CONTROLADA Trata-se de formas de onda para medição eletromagnética de fonte controlada. As formas de onda são dotadas de imagens de freqüência que incluem três ou mais freqüências espaçadas em intervalos substancialmente iguais em escala de freqüência logarítmica e ligando uma largura de faixa de em torno de uma dezena ou mais, em pelo menos três das quais as freqüências são dotadas de amplitudes correspondentes aproximadamente iguais.
