摘要
研究了空间绕飞任务中主、从航天器之间的电磁干扰问题,提出了绕飞过程中航天器间电磁兼容仿真分析方法。根据主、从航天器天线的发射功率、带外抑制、接收机灵敏度的信息,解算出了发射天线对接收天线的等效干扰。在假定计算模型作为仿真输入的前提下,得到了航天器间电磁兼容分析结果。仿真结果表明,所提出的仿真分析方法能够对绕飞任务中航天器间的电磁干扰进行预测,可为实际任务的顺利完成提供技术支持。
The problem of electromagnetic interferences between spacecraft for space fly-around mission is investigated, and a simulation approach of electromagnetic compatibility between spacecraft for space fly-around mission is presented. According to the transmission power, out-of-side rejection and sensitivity of receiver, the equivalent interferences between transmitting and receiving antennas are calculated. In the precondition of the assumed model, the simulation results of electromagnetic compatibility are obtained. Simulation results show that the approach proposed in the paper can achieve the goal of forecasting the electromagnetic interferences between spacecraft during fly-around mission.
