提出了将相位干涉仪与MUSIC相结合的算法,先利用相位干涉仪算法对目标进行定位,然后在一定的范围内利用MUSIC算法进行谱峰搜索,这样既提高了L阵相位干涉仪的测角精度同时又缩小了搜索时间,有效地提高了MUSIC算法的效率。同时通过对L阵相位干涉仪、相关干涉仪、MUSIC谱估计和文中提出的联合算法的测向精度和MATLAB虚拟环境中的耗时仿真,结论表明此方法可以有效地解决精度高和实时性好这一矛盾。
The algorithm of combining phase interferometer and MUSIC is proposed. The phase interferometer algorithm is used to locate the target first, and then the MUSIC algorithm is used to search the peak within a certain range. This not only improves the measurement angle of L array phase interferometer The accuracy also reduces the search time and effectively improves the efficiency of the MUSIC algorithm. At the same time, the accuracy and real-time accuracy of the L-array phase interferometer, the related interferometer, the MUSIC spectrum estimation and the joint algorithm’s direction finding accuracy and the time-consuming simulation in the MATLAB virtual environment are analyzed. This contradiction.
