功率最小化是卫星导航系统中干扰抑制的传统方法。它适用于干扰远强于有用信号和噪声的情况，其主要优点是不需要有用信号的到达方向（DOA）信息。本文提出了一种基于天线阵列抑制卫星导航强干扰的新方法。我们的想法是用接收阵列信号的主要成分代替传统功率最小化方法中的辅助天线输出，从而提高性能，正如我们的模拟所验证的那样。
Power minimization is a traditional method for interference suppression in satellite navigation systems. It works when the interferences are much stronger than the desired signals and noise, and its main advantage is that the direction of arrival (DOA) information of the desired signals is not required. In this paper, a new method for suppressing strong interferences for satellite navigation based on antenna arrays is proposed. The idea is to replace the auxiliary antenna outputs in the traditional power minimization method by the principal components of received array signals, leading to an improved performance, as verified by our simulations.
