    • The invention provides a reflective material, adapted for the efficient retro-reflection of radiation emitted by radar, the material comprising a multiplicity of reflective entities which are typically embedded in a substrate, the multiplicity of reflective entities being comprised in at least one reflective surface or electrically conducting surface, and the at least one reflective surface or electrically conducting surface comprising an electrically conductive coating, a high permittivity material, a foil, a film or a fabric formed from electrically conducting fibres or filaments. The reflective entities may comprise discrete shaped entities, most preferably di- or tri-hedral shaped entities, which are preferably embedded in a high permittivity medium. More preferably, the reflective entities are comprised in the machined surface of a reflecting substance comprising a polymeric sheet material which is machined to provide an irregular patterned surface. Most preferably, the substrate comprises a textile material in the form of a garment. Reflective material and textile garments according to the invention provide a highly efficient means for the reflection of incident radar radiation and offer significant benefits in terms of the visibility of wearers to drivers of oncoming vehicles in poor and dark light conditions, thereby facilitating a marked improvement in road safety statistics and enhancing search and rescue detection and success rates, especially in severe and inclement weather conditions.
    • 本发明提供了一种反射材料,适用于对由雷达发射的辐射的有效回射,该材料包括多个反射实体,这些反射实体通常嵌入在基底中,多个反射实体包含在至少一个反射表面或 所述至少一个反射表面或导电表面包括由导电纤维或细丝形成的导电涂层,高介电常数材料,箔,膜或织物。 反射实体可以包括离散的成形实体,最优选二或三角形实体,其优选地嵌入在高介电常数介质中。 更优选地,反射实体包括在反射物质的加工表面中,反射物质包括被加工成提供不规则图案化表面的聚合物片材。 最优选地,基底包括衣服形式的纺织材料。 根据本发明的反光材料和纺织品服装提供了一种用于反映入射雷达辐射的高效手段,并且在不良和暗光条件下,对穿戴者对迎面而来的车辆的驾驶员的可视性方面提供了显着的益处,从而有助于显着改善 道路安全统计数据,加强搜索和抢险检测和成功率,特别是在恶劣天气条件下。
