Abstract
Un sistema de antena, tales como un sistema de antena de radar, que incluye una matriz de elementos de antena y un controlador. El controlador produce un indicador dentro de la trayectoria en respuesta a un ángulo de llegada para un objetivo que es menos que un ángulo umbral para un rango dado hasta el objetivo. El ángulo de llegada se basa en un ángulo de fase diferencial derivado de datos que definen un primer y segundo retornos de señal compuesta desde el objetivo asociados a la primera y segunda aberturas respectivamente, y un centro de fase descentrado entre las aberturas. La primera y segunda aberturas se forman a partir de un primer y segundo subconjuntos de los elementos de antena respectivamente.
