| 摘 要： | 在实际中接收天线与辐射源之间通常存在相对运动，此时传统的高分辨算法性能将严重下降，针对上述问题提出一种自适应信号波达方向即DOA估计算法。新算法以快速稳定的信号子空间跟踪算法为基础，结合ESPRIT算法实现DOA估计，不需要特征值分解，计算复杂度小。仿真实验显示新算法比基于幂迭代的动目标DOA估计算法具有更好的估计性能。

| Abstract: | In reality,the receiving antenna and the radiation sources are commonly found relatively moving,and the performance of traditional high-resolution algorithm will be severely curtailed.An adaptive Direction of Arrival (DOA) estimation algorithm based on fast and stable subspace tracking method was proposed for the above issues.And ESPRIT algorithm was adopted to estimate the DOA without eigen decomposition,thus the novel algorithm has lower computational complexity than the conventional algorithms.The simula... |
