Abstract: Carcasa de radomo que comprende paredes (6, 11) de material compuesto que incluye fibras de refuerzo (8) y resina de matriz (19) que unen las fibras, las paredes que incluyen una ventana de transmisión de radiación (11) a través de la cual la radiación de una antena de radomo (2) pasa cuando la antena de radomo (2) se monta dentro de la carcasa del radomo (1), en donde las paredes están compuestas por un perfil tubular recto o en forma de C y la cantidad de fibras en la ventana de transmisión de radiación (11) es menor que 40 % de la cantidad de fibras de refuerzo en otras partes de las paredes de la carcasa (6), y que la ventana de transmisión de radiación (11) tiene una estructura de sándwich que tiene capas superficiales (13) y una capa intermedia (12) entre las capas superficiales, las fibras de refuerzo que se concentran en las capas superficiales (13) y la capa intermedia (12) que se hace de un material de relleno (9).

Abstract: Invention relates to a radome casing and method for its manufacturing. The radome casing comprises WALLS (6, 11) of composite material which includes reinforcement fibers (8) and matrix resin (19) binding the fibers together. The walls include a radiation transmission window (11) through which the radiation of a radome antenna passes when the radome antenna (2) is mounted inside the radome casing (1). The amount of fibers in the radiation transmission window (11) is reduced to be less than 80-5% of the amount of fibers elsewhere in the casing walls (6). The reduction of reinforcement fibers in the radiation transmission window (11) reduces attenuation of the high frequency radiation.
