| 摘 要： | 大型火箭二次点火时,排放出的尾气中含有大量的化学物质(主要成分是CO2和H2O),可以显著改变电离层密度,进而影响电波的传播,因此具有现实的应用价值.讨论了火箭尾气在电离层高度的扩散过程和相应的离子化学过程,理论计算了火箭尾气排放后电离层电子密度的响应过程.结果表明,火箭所排放的尾气能够使得电离层F区的电子密度显著减少,进而形成"电子空洞".最后在此现象的启发下,简单论述了空间人工释放化学物质扰动电离层技术在军事方面的应用前景.

| Abstract: | Ionospheric F layer electron density depletions can be caused by exhaust from large rocket of the second stage propulsion,hence affecting the propagation of radio waves,which may have a profound practical application.In terms of diffusion process of neutral gas from rocket exhaust and relevant chemical reactions,the influences of injected CO2 and H2O gas on the ionosphere background are theoretically calculated respectively.The results show that the rocket exhaust gas can produce localized electron density ... |
