稳健数字波束形成算法研究

目前,自适应数字波束形成算法已经在通信、雷达等科技领域中得到了广泛的应用。但是当阵列导引向量存在误差,或测向出现偏差时,常规波束形成算法性能会急剧下降。稳健的自适应波束形成算法,则可以较好地克服上述误差带来的性能下降。针对以上问题,提出了一种稳健的Capon波束形成算法,并对现有的一些稳健波束形成算法进行了分析、归纳和比较,最后通过仿真试验来验证各种算法的稳健性。

Research of Robust Digital Beam Forming Algorithms

Self-adaptive digital beam forming algorithms have been widely used in the field of communications and radar.Performance of conventional beam forming algorithms drops sharply due to steering vector errors of array.Robust self-adaptive digital beam forming algorithms can overcome fairly well the performance degradation caused by most of the errors mentioned above.In order to solve this problem of performance degradation,this paper introduces a robust self-adaptive digital beam forming algorithm,analyses and compares some existing robust beam forming algorithms.Finally,the simulation results verify the robustness of various algorithms.
