摘要
本文结合工程实践,介绍了用6位移相器进行差信号QPSK调制,从而实现和差通道单脉冲角跟踪方案,并对相位不一致、耦合系数、同步信号的影响等问题进行了分析,给出了工程设计的方法。
Based on engineering practice, this paper introduces a scheme for the the QPSK moduoation of difference signal with 6bits phase shifter to realize sum-difference channels monopulse angle tracking, analyses such problems as the effect of phase imbalance and coupling coefficient, and also provides the design method.
