船载数字跟踪接收机自动校相新算法研究

Research on a Novel Method for Phase Auto-adjusting of TT&C Ship-borne Digital Tracking Receiver

目前船载数字跟踪接收机的自动校相算法存在一定的缺陷,为了弥补这些缺陷,提出一种新的自动校相算法,即利用解调出的角误差信号直接计算出和差通道相对相移值。针对船站特殊校相体制,重新设计优化相位修正单元,并对算法的可行性进行分析。理论分析和实验数据表明,新算法校相精度满足要求。

The current phase auto-adjusting process of ship-borne digital tracking receiver is complicated and time-consuming. To overcome these limitations,this paper presents a novel method to adjust phase more automatically.It uses the voltage of angle offset to count the phase dispersion of the two channels.The phase adjusting apartment is also redesigned and optimized according to the phase calibrating system,and the feasibility of the proposed novel method is analyzed.The results of theory analysis and experiment data show that the precision of the novel method satisfies the requirement.
