| 摘 要： | 在阵列天线MUSIC算法的工程实现中,要求用C语言实现对数据自相关阵的特征空间分解。文中参照对称矩阵特征空间分解的数值实现方法,通过在复数域中引入Householder变换和Givens变换,利用C语言编程,实现了Hermite矩阵特征空间分解,给出了迭代算法。在迭代算法中,采用直接数据置换降低矩阵维数,节省了存储空间,提高了运算速度。在PC104上编程,实测结果表明算法稳定,结果正确,运算速度满足工程的需要。

| Abstract: | It is needed in engineering realization of MUSIC algorithm to decompose the eigenspace of Hermite Matrix in C language.Referring to the data realization of the eigenspace decomposition of symmetry matrix,the Householder Transform and Givens Transform were introduced to complex field.The iterative algorithms in C language were given,which used direct data replacement to reduce the dimension of matrix and saved the storage space.The measurement results on pc104 show that the algorithm is stable and the results is correct. |
