Abstract

"MéTODO PARA CHECAGEM DE RADIOALTìMETRO TIPO FM/CW, E RADIOALTìMETRO PROJETADO PARA A IMPLEMENTAçãO DESTE MéTODO". Um radioaltímetro que utiliza um oscilador linear para enviar uma onda contínua que é linearmente modulada em freq³ência entre dois valores limites envia para a instalação da antena um sinal incidente, coleta o sinal refletido pela instalação e examina-o. Para a instalação da antena de recepção, isto significa propiciar um reencaminhamento com a finalidade de orientar uma pequena parte do sinal do oscilador para esta instalação. No caso da instalação da antena de transmissão é suficiente propiciar um reencaminhamento que injete o sinal refletido por esta instalação para o canal de recepção. Aplicação para todos os radioaltímetros FM/CW.
