| 摘 要： | 分析了利用三元阵抵消干扰的方向特性,主要分析了当期望信号偏离基阵的垂线方向或对期望信号的传播方向的估计存在误差时和当干扰的传播方向接近于期望信号的传播方向时,提取出期望信号相对误差的大小相关性.结果表明：提取期望信号的相对误差主要取决于期望信号传播方向与基阵垂线的夹角,而干扰与期望信号的幅度比及它们频谱之间的相位差对相对误差的影响较小.

| Abstract: | Direction property of suppressing interference suppression by using three - sensor array is analyzed in this paper. Relative error expression of extracted signal is also studied in two different cases. Resuits show that the relative error expression of extracted signal relies on the angle between the transfer direction of expected signal and the vertical direction of array, less relying on the amplitude ratio between the expected signal and the interference as well the phrase difference of their spectrum. |
