The high temperature insulation and wave-transparent characteristics of SiO2 aerogel were analyzed. Compared to insulation materials and wave-transparent materials commonly used, SiO2 aerogel material has a lower thermal conductivity and a lower dielectric constant, is a kind of material with good performance on high temperature insulation and wave-transparent. The principle for wide-band transparent of sandwich structure radome was analyzed, and research progress of the sandwich structure radome was reviewed. The results showed that, because of its high temperature insulation and wave-transparent characteristics, SiO2 aerogel material can meet the needs of the inner materials of the sandwich structure radome, and is bound to be widely used in the sandwich structure radome.
