| 摘 要： | 功率倒置算法适用于全球定位导航系统等期望信号弱而干扰较强的场合。针对弱干扰源时,功率倒置算法阵列方向图在干扰方向零陷深度不够,干扰抑制效果不理想的问题,本文在分析功率倒置算法实质的基础上,提出基于矩阵重构的改进算法,对弱干扰取得了满意的抑制效果。

| Abstract: | Power inversion （PI） algorithm is suitable for Global Satellite Navigation System （GNSS）, in which sig- nal is weak while interference is strong. But the null depth formed by power inversion algorithm is not deep enough when the interference power is weak. In order to improve the anti-interference performance of PI algorithm, an im- proved PI algorithm based on matrix reconstruction is proposed based on analysis of essence of PI algorithm. Good anti-interference performance against weak interference is obtained. |
