摘要
详细描述了“黑障”产生的原因、对电波传播的影响、等离子体电特性参数;作为一次练习,估算了测控通信系统的工作频率、电波穿过“黑障”区的衰减常数;讨论了空天飞机测控通信体制、主要的系统功能和关键技术。
The generation reason of blackout, its effect on the propagation of electromagnetic wave and the electrical characteristic parameters of plasma are described. As an example, the operation frequency of TT＆C and data transmission（TTC＆DT） and the attenuation constant of electromagnetic wave through the blackout zone are estimated. The TTC＆DT system, main functions and key technology of spaceplane are also discussed.
