摘要

针对波束域算法分辨率低和高分辨空间谱估计算法对噪声敏感而导致的复杂电磁环境下定位精度低的问题，提出一种Capon和Root-MUSIC的联合算法（CRMU），用于短波单站一维定位技术的研究。该算法不仅能避免谱峰搜索带来的高运算量，还能在实际探测中，抑制噪声对信号的影响，从而降低方位角估计均方根误差。在仿真模型中，CRMU算法的输出方位角角度估计的均方根误差至少比Root-MUSIC算法小0.2°。在短波单站一维定位实际应用中，CRMU算法的定位误差均在3%以下，满足了定位误差5%以内的实际工程需求。

Abstract

With the low sensitivity of beam field and noise-sensitive of high resolution spatial spectrum algorithm

the low location precision under the complex electromagnetic environment becomes a severe problem.The Capon and Root-MUSIC (CRMU) joint algorithm was proposed to research the one-dimensional location technology.The proposed algorithm could not only avoid the high operation caused by the peak search but also suppress the noise

which contributed to reduce the root mean square error (RMSE) of azimuth.Then

the simulation results demonstrate that the RMSE of the proposed algorithm is at least 0.2 degrees less than that of the Root-MUSIC algorithm.In addition

the location error of the proposed algorithm is less than 3% in the practical application of one-dimensional location of shortwave single station

which satisfies the demand that the location error should be below 5%.
