Abstract

Un método para detectar los parámetros de movimiento de un objetivo con base en tierra mediante el procesamiento de las primera y segunda secuencias temporales de los retornos de un sistema de apertura sintética, cada secuencia recogida durante los pasadas de formación de imágenes separadas, los retornos que comprenden una pluralidad de imágenes de base de apertura sintética de una región caracterizado porque comprende las etapas de: i) emparejar una imagen en la segunda secuencia temporal con una imagen primaria correspondiente de la primera secuencia temporal, alinear las imágenes si se requiere y conformar una imagen de detección de cambios CCD coherentes, y repetir para cada par para producir una pluralidad de imágenes de base CCD; ii) conformar una imagen de referencia a partir de una o más de las imágenes de base CCD; iii) conformar una imagen de "detección de cambios ICD incoherentes" mediante la normalización de la imagen de referencia con una imagen de base CCD predeterminada convenientemente alineada a partir de la secuencia; iv) analizar la imagen ICD para detectar un rastro dejado por el objetivo; y v) detectar un objetivo mediante la producción de una o más imágenes enfocadas mediante la manipulación de las fases de los retornos temporales de acuerdo con los parámetros de movimiento estimados a partir del rastro de un objetivo.
