| 摘要 |
The present invention discloses a system and a method for reducing plasma induced communication disruption utilizing electrophilic injectant and sharp reentry vehicle nose shaping. Injecting electrophilic gas into plasma accomplishes reduction of plasma induced communication disruption by removing free electrons in the plasma which causes the communication disruption. For reentry vehicles, a multi-section sharp nose also reduces plasma effect during reentry. By combining electrophilic gas injection and a multi-section sharp nose shaping, the present invention reduces and further eliminates plasma induced communication blackout, such as GPS communication blackout, for a reentry vehicle during reentry. As a result, the present invention improves targeting accuracy for a GPS-guided reentry vehicle by reducing plasma induced GPS blackout during the critical reentry phase.
