Abstract

Sistema de radar de apertura sintética con un cierto número de n sistemas de radar SAR sobre plataformas portadoras apoyadas en satélites o cuerpos voladores, que se mueven en una formación prevista, que están dispuestos a distancia prevista unos de otros y cuyas direcciones visuales de antena están orientadas sobre tierra sobre la misma zona iluminada mediante impulsos de microondas, en el cual los múltiples conjuntos de datos SAR obtenidos son combinados en concordancia de fase en un procesador de señales formando una imagen SAR con resolución geométrica aumentada, caracterizado porque las distancias entre las plataformas portadoras en la dirección de vuelo y los ángulos visuales de las antenas están ajustados de manera que son registradas diferentes zonas espectrales espaciales de la señal retrodispersada desde tierra con un determinado solape de los espectros de azimut o espectros Doppler.
