基于MUSIC算法的相位干涉仪测向

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。

Direction Finding of Phase Interferometer based on MUSIC Algorithm

The algorithm in combination of phase interferometer with MUSIC is proposed. Phase interferom- eter method is employed to find the direction first, then MUSIC to search the peak spectrum in certain scope. And thus the angular-measuring accuracy of L array phase interferometer method is assured while the searching time of MUSIC method reduced. Simulations on L array phase interferometer , L array-correl- ative interferometer,L array MUSIC spectral estimation, direction-finding accuracy of the proposed joint algorithm and time-consuming in MATLAB virtual environment indicate that this method could effectively solve the oroblem of high nrecision and zood real-time nerfarmance.
