Embodiment Construction

[0018] The present invention will be further illustrated below through an implementation case.

[0019] The car cover adopts composite material sandwich structure, see image 3 .Schematic diagram of the three-layer structure of the vehicle-mounted radome. The sandwich structure is composed of weather-resistant wave-transparent exterior coating 1, fiber fabric reinforced composite material outer skin 2, foam or honeycomb core material 3, fiber fabric reinforced composite material skin 4, wave-transparent inner surface coating 5, etc., through surface spraying The weather-resistant wave-transparent coating with a thickness of tp (tp≤0.5mm) effectively improves the weather resistance and camouflage concealment of the product without affecting the electromagnetic performance of the vehicle cover; by adopting the thickness tf (tf: each layer of mask The thickness of the skin, tf≤2mm) fiber fabric reinforced composite skin, which effectively improves the mechanical properties of th...

Abstract

The invention discloses a manufacturing method of a wind shield for a vehicular radar, relates to a windshield for a vehicular radar not affecting the normal working of a radar antenna, and in particular to a composite material sandwich structure product coordinating with the exterior and the color of a vehicle body. The composite material sandwich structure comprises a wave transparent exterior coating material with weather resistance, fabric reinforced composite material outer skin, a plurality of layers of intermeshed overlaid core material and fabric reinforced composite material outer skin such as foam or honeycomb and the like, and a wave transparent inner surface coating material in sequence. On the premises of satisfying an electromagnetic performance index and structural mechanics mechanical property, the camouflage property and invisibility of the radar antenna are improved, and the serviceability, validity, availability, service life, effectiveness-cost ratio, and the like can be improved.

Description

technical field [0001] The invention relates to the field of radar antennas, in particular to the technical field of vehicle-mounted radomes. Background technique [0002] The radome radome is also called Electromagnetic Windows (Electromagnetic Windows), and its English name is Radome (abbreviation of Radar Dome). The required electromagnetic characteristics are mainly used to prevent the adverse environment from affecting and interfering with the working state of the radar antenna without affecting the transmission or reception of electromagnetic waves by the radar antenna, to ensure the normal operation of the radar under various working conditions around the clock, and to improve the radar performance. Use availability, service life and cost-effectiveness. In view of reducing the influence of the radome on the electromagnetic performance of the radar antenna and improving the structural mechanical properties of the radome, the appearance is usually a truncated spherical...
