大口径船载卫通站一般采用单脉冲跟踪方式，需要高次模耦合出的差信号与通信网络输出的和信号经和差网络合成后输出误差信号用作解调跟踪。这种方式要求通信与跟踪极化方式需相同，限制了卫通站的使用，分析了馈源网络的基本结构以及单脉冲跟踪的工作原理，提出通信低噪采用2∶1低噪冗余控制系统代替1∶1冗余控制系统，可以实现通信极化与跟踪极化的分离，从而实现固定跟踪A极化信标，通信根据需要灵活选择A极化或B极化转发器，提高了船载卫通站使用的灵活性。

The monopluse tracking mode is usually adopted in large-aperture shipborne satellite communication station. The output error signal is composed of the difference signals coupled with high-order mode and the sum signals from communica-tion network through sum-difference network synthesis for demodulating and tracking. This mode required same tracking polariza-tion and communication polarization,so it limits the application of satellite communication station. The basic structure of feed source network and the working principle of monopluse tracking are analyzed in this paper. The 2:1 low-noise redundancy control system was adopted instead of 1:1 low-noise redundancy control system. It can realize the tracking and communication polariza-tion separation,and can track the A polarization beacon. The flexibility of shipborne satellite communication station was im-proved by flexible selection of A or B polarization transponder.
