摘　　要：利用圆波导圆极化TE11模、TM01模和线极化TE21模可以构成跟踪圆极化来波的三信道真单脉冲系统、伪单脉冲系统及电子波束偏转跟踪系统。分析表明这3种跟踪系统角误差电压交叉耦合的表达式是相同的。这3种系统的交叉耦合与圆波导TE11、TM01模真或伪单脉冲系统的交叉耦合实质上是相同的，因此仅当来波轴比优于．5dB时上述3种系统才能正常工作，这在我们预料之中。The three channel （true） monopulse system, the pseudo monopulse system and the electronic beam squint tracking system can be composed on the basis of the circular polarization TEll mode, TM01 mode and linear polarization TEE1 mode in the circular waveguide. It shows that the cross talk in the angle error voltages of these systems is the same, and theirs cross talk is the same as the cross talk of the circular waveguide TEll and TM01 mode true or pseudo monopulse system, then the three tracking system can operate normally only when the axial ratio of the incoming wave is better than -5 dB.
