Abstract

Se describen métodos, sistemas y dispositivos para el seguimiento de señales de eventos pasados. En algunos ejemplos, un sistema puede recibir señales de elemento de alimentación correspondientes a un conjunto de elementos de alimentación de una antena. Para soportar una misión primaria o en tiempo real, el sistema puede procesar las señales de elemento de alimentación de acuerdo con una primera configuración de formación de haz para generar señales de haz puntual, que pueden incluir comunicaciones programadas para los haces puntuales respectivos. Para soportar una misión retroactiva o de búsqueda, el sistema también puede almacenar las señales de elemento de alimentación durante una cierta duración. Basado en una determinación para la búsqueda de una señal objetivo desde una ubicación objetivo dentro de un área de cobertura de la antena, el sistema puede procesar las señales de elemento de alimentación almacenadas de acuerdo con una segunda configuración de formación de haz para generar una señal de haz puntual objetivo correspondiente a la ubicación objetivo, y evaluar la señal de haz puntual objetivo para una presencia de la señal objetivo.
