Abstract

The invention discloses a millimeter wave radar thermal insulation wave transparent radome. The radome includes a substrate. A colored layer, a nanometer metal level, an antioxidation layer, a paint inner protective layer and a base are inwardly arranged on the substrate in order. A wave transparent thermal insulation layer and a paint outer protective layer are outwardly arranged on the substratein order. The wave transparent thermal insulation layer is porous silicon nitride ceramic. The sign of the radar radome has good metallic luster, the wave transparent performance is excellent, the performance of sound and shock absorption, heat preservation, strength, rain corrosion resistance and ablation resistance is good, and usage requirements of customers can be met.

Description

technical field [0001] The invention relates to the field of millimeter-wave radars, in particular to a heat-insulating and wave-transmitting radome for millimeter-wave radars. Background technique [0002] The radome is a multifunctional wave-transparent structure used to protect communication, telemetry, guidance, detonation and other systems to work normally in various service environments. widely used in the system. [0003] With the development of millimeter wave technology and the improvement of anti-interference requirements, the material and structure design of wide-band, multi-band and even ultra-wideband radome has become one of the hot spots of research at home and abroad. The wave-transmitting structure of the existing radome has high transmission and reflection loss, low wave-transmitting performance, and poor mechanical properties such as strength and stiffness of the overall structure, making it difficult to meet increasing customer demands.
