Abstract

Procedimiento de estimación de la elipticidad T de polarización de una señal de respuesta de antena de cuadros cruzados o de una red de antenas de tipo Adcock a una onda electromagnética incidente recibida en dicha antena, caracterizado porque incluye al menos las etapas siguientes: - medir el desfase Δφ entre las señales adquiridas respectivamente en la vía coseno y seno de la antena (401); - medir la relación R entre las amplitudes de las señales adquiridas respectivamente en la vía coseno y seno de la antena (402); - determinar el ángulo de elipticidad T en función del desfase Δφ y de la relación R (403).
