Abstract

UN SISTEMA DE DETECCION DE SEÑAL DEL ESPECTRO DE PROPAGACION COMPRENDE DOS RECEPTORES SEPARADOS ESPACIALMENTE, UN CORRELADOR, TAL COMO UN CORRELADOR INTEGRADOR DE TIEMPO QUE EMPLEA CELDAS ACUSTICO-OPTICAS, EL CUAL ESTA CONECTADO A LAS SALIDAS DESDE LOS DOS RECEPTORES PARA PRODUCIR UNA SEÑAL REPRESENTATIVA DE LA FUNCION DE CORRELACION CRUZADA DE LAS DOS SEÑALES DEL ESPECTRO DE PROPAGACION, UN FILTRO COLOCADO PARA TRANSMITIR SOLO LA PARTE CENTRAL DE LA FUNCION DE CORRELACION CRUZADA Y UN PROCESADOR DE SEÑAL PARA PRODUCIR LA DENSIDAD ESPECTRAL CRUZADA Y DETERMINAR ASI LA PRESENCIA DE LA SEÑAL DEL ESPECTRO DE PROPAGACION. LA DIRECCION DE LLEGADA DE LA SEÑAL DEL ESPECTRO DE PROPAGACION SE PUEDE DETERMINAR MIDIENDO EL ANGULO DE LA PENDIENTE DE FASE DE LA DENSIDAD ESPECTRAL CRUZADA. LAS CELDAS ACUSTICO-OPTICAS PUEDEN SER CELDAS DE BRAGG. LA SEÑAL DE SALIDA DE UNO DE LOS RECEPTORES SE PUEDE APLICAR A UNA PRIMERA CELDA DE BRAGG COLOCADA PARA DIRIGIR LUZ MODULADA DESDE UNA FUENTE DE LUZ LASER, LA SALIDA ES TRANSMITIDA DESPUES A TRAVES DE UN DISPERSOR DEL HAZ HACIA UNA SEGUNDA CELDA DE BRAGG A LA CUAL SE PUEDE APLICAR LA SEÑAL DE SALIDA DEL SEGUNDO RECEPTOR, LA SALIDA DE LA SEGUNDA CELDA DE BRAGG SE DETECTA ENTONCES POR UNA MATRIZ FOTODETECTORA. LA SALIDA DE LA SEGUNDA CELDA DE BRAGG PUEDE SER FILTRADA ESPACIALMENTE PROPORCIONANDO OPTICA DE FORMACION DE IMAGENES AJUSTABLE COLOCADA DE FORMA QUE SOLO SE TRANSMITE LA LUZ CORRESPONDIENTE A LA PARTE CENTRAL DE LA FUNCION DE CORRELACION CRUZADA. EL PROCESADOR SE PUEDE UTILIZAR PARA DESMODULAR LAS SEÑALES PARA PRODUCIR DATOS CORRESPONDIENTES A LA PARTE CENTRAL DE LA FUNCION DE CORRELACION CRUZADA Y HALLAR LA TRANSFORMADA DE FOURIER DE LOS DATOS PARA PRODUCIR LA DENSIDAD DEL ESPECTRO CRUZADO.
