| 摘 要： | 扩频信号由于带宽宽、信噪比低，难以实现对信号的角跟踪。本文在和差信号相关法提取角误差电压的基础上，利用小部分带宽法的一些原理，提出了和差信号小部分带宽相关的方法，提高了输出信噪比。

| Abstract: | It is hard to track a DS signal because of its wide band and low SNR. Based on an angle tracking method of correlating two signals from two different channels, this paper makes use of the theory of part bandwidth method and proposes correlation of only a part band of signals to realize angle tracking. Output SNR is significantly improved. |

| Keywords: | DS signal Correlation Part Bandwidth |
