System and method for phase monopulse beam pointing

A beam pointing system is provided. The beam pointing system includes: first and second antenna segments located at first and second locations and configured to generate first and second beam signals in response to receiving a beam from a source; and a digital signal processor (DSP) communicatively coupled with the first and second antenna segments. The DSP is configured to receive the first and second beam signals, calculate a weighted phase difference signal between the first beam signal and the second beam signal by performing a phase subtraction in a complex space, an average phase difference is calculated based on the weighted phase difference signals by averaging the weighted phase difference signals over a plurality of samples, a pointing error is calculated based on the average phase difference, and a pointing of the first and second antenna segments is caused to be adjusted based on the pointing error. 提供了一种波束指向系统。该波束指向系统包括：第一和第二天线段，它们位于第一和第二位置处，并且被配置成响应于从源接收到波束而产生第一和第二波束信号；以及数字信号处理器(DSP)，它与所述第一和第二天线
