| 摘 要： | 在介绍冲击噪声的性质及其造成传统求根类算法性能下降原因的基础上,提出利用分数低阶矩(FLOM)和ScreenedRatio原理来构造阵列相关矩阵的两类求根类算法。最后通过计算机仿真对算法进行了分析和比较,结果表明该算法在性能上优于传统的算法,基于ScreenedRatio原理的算法的性能略好于基于FLOM的算法。

| Abstract: | The rooting methods for DOA estimation in impulsive noise environment are studied. Firstly the property of impulsive noise and the reasons for performance degradation of conventional DOA estimation algorithms due to such noise are introduced. Then, two types of rooting methods for DOA estimation based on fractional lower order moment (FLOM) and screened ratio principle are proposed, respectively. Finally, comparison analysis of the presented algorithms is performed. The experimental results indicate that the performance of the proposed algorithms is superior to the conventional algorithms, and the screened ratio principle based algorithm has a bit better performance than the FLOM based algorithm |
