 针对宽带多星多波束应用现状和场景，提出了数字多波束抗干扰捕获算法和高稳健性接收机整机设计实现方法。该方法基于卫星接收机，以惯导提供的航向、俯仰角和横滚角为条件，确定单约束的导向矢量，推导出空时自适应处理结构的数字多波束改进型捕获算法。仿真实验表明，改进后的算法实现了多波束数据的合理应用，能够稳定载波相位，增强空间增益，提高空域分辨率。

Application of digital beamforming anti-jamming system based on adaptive acquisition algorithm

This paper presents a brief introduction to anti-jamming technology and the current status of multi-satellite and multi-beam application, and then proposes a new digital multi-beam anti-jamming receiver implementation method. This method uses inertial device data (heading, pitch angle, and roll angle) to determine the single-constrained steering vector and further derives a digital multi-beam improved acquisition algorithm with a space-time adaptive processing structure. Simulation result shows that the improved acquisition algorithm can fully utilize multi-beam data, stabilize carrier phase, and achieve stronger spatial gain and higher spatial resolution.
