摘要

提出了一种基于最小均方法的数字波束形成算法的空时自适应处理器。进一步介绍了该算法在卫星导航领域应用的全向优化原理。该算法最大限度地减少了天线小型化设计中由于衬底不对称的边缘效应而引起的辐射方向图偏差。通过辐射方向图实验、卫星信号接收实验和抗干扰实验,验证了算法的抗干扰性能。

Anti-jamming space-time processor with digital beamformer for satellite navigation
This paper presents a novel space-time adaptive processor with digital beam forming algorithm based on least mean squares (LMS) method. Furthermore, the omnidirectional optimization principle for the algorithm applied in satellite navigation field is introduced. The algorithm minimizes the deviation of the radiation pattern due to the edge effect of asymmetric substrate in the miniaturization design of antennas. The anti-jamming performance of the introduced algorithm is verified through the experiment of radiation pattern, satellite signal receiving experiment and anti-jamming experiment.
