宽带的稳健自适应阵列处理

Robust Broad-band Adaptive Array Processing

提出了一种宽带的稳健自适应阵列处理的方法。通过对权矢量的二次型约束可有效地克服因阵元位量随机扰动、通道幅相特性变化、信号波前畸变、通道失配及约束方向失配等不可预见的随机因素引起的性能下降，通过计算机仿真验证了这种宽带稳健算法的优越性并给出了数值结果。

A new approach to the design of robust broad-band adaptive array processor is presented in this paper.While the quadratic constraint on the weighted vector is developed, the robust feature of the designed array processor is provided in presence of robustness against array geometry errors, channel amplitude/phase errors and wavefront distortions and directional misalianment and channel mismatch. Computer simulation has been established and numerical results show that the performance of this new algorithm is satisfactory and effecient for the robust broad-band processor.
