首先介绍了采用TM01模为和模、TE21模为差模的单通道单脉冲跟踪体制的工作原理，其次给出了一种数字化跟踪接收机的设计方案。通过分析和通道与差通道相位差对跟踪性能的影响，提出了可应用于跟踪接收机设计的一种采用过零点检测加数字移相补偿的方案，并对该方法的性能进行分析，最终在试验样机中相位补偿的前后交叉耦合的比对。该方法与跟踪系统的频率无关，且具有很好的稳定性。通过在试验系统中应用，结果表明该方法可以快速校准相位误差，系统交叉耦合性能满足设计要求，跟踪过程工作稳定、可靠。

First of all, the working principle of the single pulse tracking system,in which TM01 mode is the common mode and TE21 mode is the differential mode, was demonstrated in the paper. Secondly, a designing scheme of the digital tracking receiver was presented. The influence on the tracking performance by phase difference between the common channel and the differential channel was analyzed. And a zero cross point detection plus digital phase shift compensation method was proposed, which could be implemented in a tracking receiver design. The performance of this method was carried out. In experimental prototype, the cross coupling comparison before the phase compensation and after was presented at last. This method which is given in the paper has very good stability and is independent of frequency of the tracking system. The application in experimental system shows that this method can calibrate phase error with a very high speed. And the cross coupling performance of the system satisfies the design requirement. The tracking process is stable and reliable.
