摘要
二维虚拟ESPRIT算法对子阵列内部结构要求低,但在低信噪比环境下,其估计误差较大。提出一种改进的二维虚拟ESPRIT算法,该算法具有二维虚拟ESPRIT算法的优点,但在低信噪比条件下他的估计误差更小,算法运算量更低。计算机仿真实验表明了改进的二维虚拟ESPRIT算法的有效性。
2- D virtual ESPRIT algorithm has a low requirement for inner structures of subarrays. But in low SNR situations,its estimating error will be reduced. This paper presents an improved method whose estimating errors are lower than that of the original method in low SNR environments,and it also can decrease the computation cost. Its effectivity can be proved by the computer emulating results.
