O QUE SIGNIFICA DIRECTION FINDING EM INGLÊS
Pesquisa de direção
Pesquisa de direção ou busca de direção de rádio, refere-se à medida da direção a partir da qual um sinal recebido foi transmitido. Isso pode se referir ao rádio ou a outras formas de comunicação sem fio. Ao combinar a informação de direção de dois ou mais receptores adequadamente espaçados, a fonte de uma transmissão pode estar localizada no espaço através de triangulação. A detecção de direção de rádio é usada na navegação de navios e aeronaves, para localizar transmissores de emergência para busca e resgate, para rastrear animais selvagens e para localizar transmissores ilegais ou interferentes. Os sistemas RDF podem ser usados com qualquer fonte de rádio, embora o tamanho das antenas do receptor seja uma função do comprimento de onda do sinal - os comprimentos de onda muito longos requerem antenas muito grandes e geralmente são usados apenas em sistemas terrestres. Esses comprimentos de onda são, no entanto, muito úteis para a navegação de rádio marítima, pois podem percorrer distâncias muito longas "ao longo do horizonte", o que é valioso para os navios quando a linha de visão pode ser apenas algumas dezenas de quilômetros. Para uso aéreo, onde o horizonte pode se estender a centenas de quilômetros, podem ser utilizadas freqüências mais altas, permitindo o uso de antenas muito menores.
definição de direction finding no dicionário inglês
A definição de busca de direção no dicionário é o uso de radar, antenas, etc, para determinar a direção para fins de navegação, etc.
