摘要
单通道单脉冲跟踪以设备简单、可靠性高等特点在飞行器测控系统中获得了广泛应用。和差网络输出的和差信号相位差会影响单通道信号的调制度,进而降低跟踪精度。这种影响可以用矢量分析的方法计算出来,也可以用System-View进行仿真。可以通过相位调整的方法,在整个接收频带内获得最佳调制度,从而获得最佳的跟踪精度。
The technology of single channel monopulse tracking is widely used in air vehicle TT＆C because of its simple equipment and high reliability. The phase difference between the signals from beam forming net can affect the modulation index of single channel signal and can lower the prevision of tracking. The effect can be calculated by vector analysis and can be simulated by System-View. The optimal modulation index and precision of tracking in the full pass band can be obtained by phase adjusting.
