Abstract

1 / 1 resumo “sistema de antena, e, mã‰todo para controlar um sistema de antena direcional” um sistema de antena (1) compreende uma antena direcional (2) adaptada para girar por uma gama de direã§ãµes em azimute. ㉠responsivo a sinais de radiofrequãªncia (rf) recebidos de direã§ãµes dentro da gama de direã§ãµes em azimute. um receptor (7) estã¡ arranjado receber os sinais de rf da antena dentro de uma banda de resposta de frequãªncia de sinal do receptor e prover uma saã­da correspondente para processamento de sinal. um filtro de sinal (11) ã© operã¡vel para bloquear a saã­da do receptor quando a frequãªncia do sinal de rf se acha a uma frequãªncia dentro da banda de resposta de frequãªncia de sinal do receptor e uma unidade de detector (8) estã¡ arranjada para aplicar o filtro de sinal quando a antena direcional ã© dirigida a um azimute predeterminado ao qual uma fonte de interferãªncia estã¡ localizada e nã£o aplicar o filtro de sinal caso contrã¡rio.
