摘要
皮卫星上的测控应答机由于受体积、成本和功耗等因素限制,其性能指标比传统测控应答机差,测距、遥控和遥测信号相互干扰较为严重。重点分析了三类信号相互干扰产生的机理,获得相互干扰的不同特征,以及带来的影响。最后,根据分析结果验证了皮卫星测控应答机参数设计的合理性。
The performance of the Tracking,Telemetry,and Control (TT&C) transponder on the pica-satellite is worse than that of the conventional TT&C transponder for the limitation of volume,cost and power.So the TT&C transponder of the pico-satellite has severe interference caused by the intermodulation of the ranging,control and telemetry signals.This paper focuses on the research of the intermodulation interference brought by the above signals,gets the characteristics of different interferences and analyzes the eff...
