舰载圆形超分辨测向天线阵性能的研究

摘要

在music算法的基础上首先对其进行完善、分析，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算法对圆形超分辨测向天线阵从不同阵元半径，不同被测信号源的个数，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.%Presents the common arithmetic established by perfecting the classic music algorithm for the arbitrary antenna array in super-resolution direction estimation, briefly describes the steps to realize the algorithm to improve the classic music algorithm by inserting the data, which spreads out the range of signal to be measured,and improves the precision of the measured signal, and runs emulation with the circular array with the different radius and different signals to be measured using the music algorithm improved with matlab language.
