The Study of Performance about Antenna Array on Super-Resolution Direction Estimation

本文在music算法的基础上首先对其进行分析、完善 ,并给出了任意形状天线阵列超分辨测向的通用算法 ,简要地概括出了算法实现的具体步骤 ,同时对该通用算法做出了改进 ,提出了插值后的music算法 ,该算法能展宽测向的频率范围 ,提高了测向的精度 .然后利用music算法对均匀直线阵、均匀正方形阵、均匀圆形阵用matlab语言进行了计算机仿真实验研究 ,并给出了一些具体的实验结果 .

This paper has perfected the classic music algorithmic,analyzed and presented the common arithmetic which can be used for the arbitrary antenna array in super resolution direction estimation.this paper also summed up the steps to realize the algorithmic briefly,which also improved on the classic music algorithmic through inserting the coordination of the virtual antenna when needed.The algorithmic can spread out the range of the signal to be measured.And more the algorithmic can increase the precision of the measured signal.Then the line array、the circular array and the square array which distributed evenly have been put into emulation.The outcomes in the paper has been presented through the emulation experiment.
