【摘要】 研究了波前畸变条件下基于残缺矢量阵列的波达方向估计问题;导出了一种适用于稀疏残缺矢量阵列并对波前畸变不敏感的多子阵投影极化MUSIC方法;进一步利用线性极化状态下矢量传感器导向矢量的实值性提出了一种基于相位平滑的修正方法,该修正方法性能要优于原始方法,且可处理两个相干信号源。更多还原

【Abstract】 The problem of Direction-of-Arrival(DOA) estimation in the presence of wave-front distortion is addressed.A new multi-sub-arrays projection polarimetric-MUSIC variant is derived as an extension of scalar-array based multiple-projection MUSIC to a sparse defective vector array.The real value property of vector-sensor’ s manifold for linearly polarized signals is further used to modify the proposed polarimetric -MUSIC variant via phase smoothing,which can deal with two coherent signals.更多还原
