The invention discloses a thermal shield with the high wave transparency and the low aiming line error. The thermal shield is fixed in a radar radome, the overall thermal shield is of a rotator structure, the shape structure of the thermal shield is co-shaped with the overall internal shape of the radar radome or is co-shaped with the partial internal shape of the radar radome or is of a hemispherical structure, the thermal shield is made of oxide materials with the low dielectric constant or aerogel-based composite materials, the good thermal isolation property is achieved, and meanwhile the high wave transparent property and the low aiming line error property are achieved. According to the thermal shield, by reasonably selecting the materials and structure of the thermal shield, reflection generated between the radar radome and the thermal shield can be counteracted within a certain work frequency range to be extremely little; accordingly, on the basis of not significantly reducing the electrical properties, the thermal property of the radar radome is significantly promoted, the excellent electrical properties of wave transparency and aiming line error are kept, and the problem that the thermal isolation property of the radar radome is not good under the high temperature condition is solved.
