| 摘 要： | 提出了一种基于自适应旁瓣相消器的压制式干扰源方位估计方法。首先，利用自适应旁瓣相消器对压制式干扰信号进行抑制处理并得到一组收敛权值；然后，利用收敛权值计算出接收阵列的方向图;最后，在接收阵列方向图上寻找较深的谷值点对应的方位来估计干扰源的方位。所提方法估计精度高且易于工程实现。针对典型卫星导航接收机阵列，通过计算机仿真验证了所提方法的有效性。

| Abstract: | A direction of arrival (DOA) estimation method for jamming based on the adaptive sidelobe canceller is proposed. Firstly, a group of convergent weights vectors are obtained by the adaptive sidelobe canceller. Secondly, the beampattern is computed using the convergent weights vectors and theoretical manifold array. Finally, the azimuth angle corresponding to the notch on the beampattern is obtained by searching the notch in deep color. The estimation precision of the proposed method is higher than that of the conventional beam scanning. The method is quite applicable in engineering. The effectiveness of the method in this paper for typical receiver array is testified by computer simulation. |
