介绍了高温透波材料的研究现状,分析了现有隔热材料的隔热和透波性能.SiO2气凝胶具有优良的高温隔热性能,同时具有一定的透波能力,有可能作为一种新型高温透波隔热材料,解决高马赫数和长航时飞行器中的无线电设备的正常工作问题.%The current research status of wave-transparent materials is reviewed. The thermal insulation and wave-transparent properties of current thermal insulation materials are discussed. SiO2 aerogel has excellent high-temperature thermal insulation performance and certain wave-transparent ability. It can be used as a promising thermal insulator with wave-transparent properties to protect the radio on the aircraft flying at high Mach number and in long time.
