Abstract

SE REVELA UN EQUIPO DE PRUEBAS DE RUIDO PARA ANALIZAR LA PRESENCIA DE RUIDO (PERTURBACION) DE FASE EN UNA SEÑAL DE RADAR. SE USA UN DISCRIMINADOR POR LINEA DE RETARDO QUE HACE USO DE UN CABLE DE FIBRA OPTICA Y UNA LUZ DE LASER MODULADA POR LA SEÑAL DE RADAR. SE REVELAN METODOS DE MODULACION TANTO DIRECTA COMO INDIRECTA, EN UNION DE METODOS PARA GENERAR E INYECTAR UNA SEÑAL DE CALIBRACION.
