本文介绍了Scientific Atlanta地面站天线的单脉冲、单通道跟踪原理。由于这种跟踪能简化设备、紧凑结构,容易做到三路信号相位一致和幅度一致,容易实现自动增益控制和其他处理技术,跟踪也具有一定的精度,故受到了不少工程技术人员的重视。最后估算了跟踪精度,计算了跟踪损失。 This article describes the single pulse, single channel tracking principle of Scientific Atlanta ground station antennas. Because this kind of tracking can simplify the equipment and compact structure, it is easy to achieve the same phase and the same amplitude of three signals, easy to realize automatic gain control and other processing techniques, and the tracking has certain accuracy. Therefore, it has been paid great attention by many engineers and technicians . Finally, the tracking accuracy was estimated and the tracking loss was calculated.
