Signal Reversal of Plasma Sheath of Hypersonic Vehicles
摘要
Abstract
According to the experimental results of plasma sheath, signal reversal technology can be em-ployed to analyze the influence of plasma sheath on electromagnetic waves propagation,and the experimen-tal results can be furthermore summarized and compared with simulation results to modify the simulation models. In this paper, the signal reversal analysis method of plasma sheath is proposed, and several key technologies of signal reversal analysis are discussed,such as high-accuracy signal propagation link budget analysis,electron density measurement and prediction, evaluation of ablation and carbonization effect of spacecraft materials and electromagnetic modeling of high dynamic plasma sheath. Surmounting above tech-nical difficulty can improve the accuracy of signal reversal analysis and also makes real data modify theoret-ical analysis model more effectively.关键词
