摘　　要：对载人航天器与伴随卫星间射频设备的电磁干扰问题进行了研究,根据射频系统的收发参数建立了电磁干扰安全裕度模型,分析了伴随卫星发射天线对载人航天器接收天线的等效干扰。从保证载人航天器与伴随卫星在轨电磁兼容的角度,得到了航天器间能够兼容工作的最小相对距离计算方法。研究结果表明,所提出的分析方法能够对伴飞任务航天器间的电磁干扰风险进行预测,可为飞行任务的顺利完成提供技术支持。The electromagnetic interference(EMI) of radio-frequency(RF) equipments between human spacecraft and adjoint satellite was investigated. Based on the design of RF equipments, the model of calculating safety margin was built and the equivalent interference between transmitting antenna and receiving antenna was analyzed. To guarantee the electromegnetic compatibility, the minimal safe distance of two spacecrafts was obtained. The results show that the approach proposed in the paper can forecast the electromagnetic interference between human spacecraft and adjoint satellite, and provide technical support for the fulfillment of the mission.
