基于分数阶矩的测向算法研究

A new direction finding algorithm based on fractional order moment

在SαS噪声环境中基于阵列输出信号分数阶矩的TLS ESPRIT测向算法 ,该算法在保持了原TLS ESPRIT算法无需谱峰搜索、计算量和存储量小等优点的基础上 ,对加性SαS噪声有较好的抑制作用 ,扩展了ESPRIT算法的信号模型和应用环境。

This paper presents a fractional order moment based TLS ESPRIT direction finding algorithm in the presence of noise. The method retains the advantage of the original ESPRIT algorithm which has a low cost in computing amount and storage of array calibration data, and does not need to search over parameter space. And also, it is robust against additive noise and extends signal models and application situations of ESPRIT algorithm. The simulation results show the feasibility and effectiveness of the new algorithm.
