Abstract

Patente de Invenção: <B>"MéTODO DE ESTIMATIVA RáDIO DA VELOCIDADE DE UM MóVEL"<D>. A invenção refere-se a um método para estimar a velocidade (V) de uma estação móvel conectada por um canal de radio transmissão a uma estação remota, o referido método compreendendo as seguintes etapas sucessivas: receber e filtrar o sinal de transmissão para obter um sinal medido refletindo as variações de tempo do referido canal; determinar a função de correlação (R(<sym>)) do sinal medido parametrizado pela velocidade (V) da estação móvel; procurar o valor (R"(O)) da segunda derivação da função de correlação; . estimar a primeira derivação (<244>~ 0~) do sinal medido e computar a variação (C) da referida estimativa; identificar os resultados obtidos durante as duas etapas (R"(0) = C) precedentes.
