摘要
为了提高中低轨卫星(中继终端)向中继卫星传输数据的性能,将TE21模单通道单脉冲技术应用到中继终端自动角跟踪系统中提出了一种新的设计方法。通过将差信号进行四相调制后再与和信号合成,使和、差信号合成为一路单通道信号。该方法与现有的方法相比,大大简化了跟踪接收机。用Matlab/Simulink对不同的参数下跟踪接收机的输出进行了仿真分析,不同的参数对跟踪接收机的输出有不同的影响。该方法具有很好的接收性能。
In order to improve the performance of data transmission from LEO satallite（Relay Terminal） to relay satellite,in this paper we apply the TE21 mode single-channel single-pulse technology to the relay terminal automatic angle tracking system and propose a new design method.The single-channel signal is a synthesis of sum signal and difference signal by four-phase modulating diffenence signal.Compared with existing methods,this method greatly simplifies the tracking receiver. We also simulate and analyse the output of the tracking receiver in different parameter by using Matlab/Simulink.Different parameters have different effects on the output of the tracking receiver.This method has very good reception performance.
