Abstract

Se diseña un radar para automóviles de alto rendimiento y bajo costo mediante el montaje de receptores alrededor de una lente de Luneburg impresa en 3D. Con esta configuración, el patrón de radiación de la antena se mantiene para todos los ángulos (lo cual significa que no existe deformación del haz). Además, el radar actual es capaz de realizar la detección en todos los ángulos de acimut y elevación con alta resolución de ángulo y operación de banda ancha. El radar ajusta de manera adaptativa su patrón de detección espacial, banda de frecuencia de barrido, frecuencia de repetición de pulso e intervalo de procesamiento coherente de acuerdo con el entorno. Esto se logra al realizar inicialmente un escaneo aproximado, que actualiza los resultados de la detección a través de una forma de onda de ancho de banda estrecho y un escaneo de haz amplio. Cuando se identifican los objetos de interés, se realiza un escaneo detallado de alta resolución en una región específica de interés. De esta manera, puede obtenerse una detección mucho más efectiva. Además, se describe un método para mitigar la interferencia del radar basado en lentes de Luneburg impresas en 3D y un método para mejorar la resolución de ángulos mediante el uso de un enfoque MIMO basado en lentes.
