In the hypersonic flight conditions,the radome will have to face the contradiction between the mechanical, thermal and electrionics in electrical structure design. In order to solve this contradiction,this paper apply the impedance matching techniques,introduce the permittivity matching layer between the mechanical layer and the heat insulation layer. Using this techinque,the electrical property have been significantly improved based on satisfying the mechanical property and the thermal property. The application of this techniques can provide a feasible technical way for traditional area of electrical structure design, and can effectively solve the bottleneck problem of designing high temperature radome and other high performance radome. |
