摘要
采用的是加权多目标分类算法(WMUSIC方法)来提高空间方位估计的方法。它利用阵列输出的协方差矩阵中噪声空间较好的估计多目标的方位,是一种超分辨率的方位估计算法,具有比传统MUSIC更好的分辨率和精确度。本文对其进行了详细的阐述及计算机仿真。
In this paper,the method of improving DOA estimation performance for space signals by using an adding-weight multiple singnal classification algorithm is presented. It shows that an acceptable result through using noise space in covariance matix of array output, so that it is possible to improve the DOA estimation accuracy for high resolution signal. Finally, the performance of estimators and precision of method is given by computer simulations.
