“…The thermal expansion coefficient of most radome materials is in the range of ( 2.5 ∼ 4.0) × 10 −6 /K [28][29][30]. Therefore, α is taken as 4.0 × 10 −6 in the subsequent analysis.…”

The radome is an important component of the aircraft seeker. The radome of high-speed aircraft usually has ablation, which affects the electromagnetic performance of the radome. Therefore, it is important to study the electromagnetic performance of the radome wall during high-temperature ablation. However, most existing studies mainly consider the influence of temperature and ignore structural changes caused by ablation. To solve the above problems, this paper studies the influence of ablation on the electromagnetic performance of inhomogeneous radome walls (IRW) by considering the structure parameters, thermal expansion characteristics, and dielectric parameters during the ablation. The two typical types of IRW design methods are analyzed, the parameters calculation method in the ablation process is proposed, and the influence of ablation on the two types of IRW is studied. The results give the electromagnetic changing characteristics of the IRW under different ablation conditions. The contribution of this work is to lay a solid theoretical foundation for improving the performance of the radome in the ablation process, which is of great significance.

“…HfO 2 system, that is Ta 2 O 5 and HfO 2 would have very low affinity for each other and do not form a solid solution with appreciable solubility[94]. The implication is that, despite the careful efforts in solution processing to mix Ta and Hf salts uniformly (e.g., via the use of an organic solvent), the oxides of tantalum and hafnium, which can exist in amorphous form, will always segregate into separate Ta 2 O 5 and HfO 2 regions.…”
