high_resolution_frequency_estimation

1.If the space shift invariance is replaced by the time shift invariance, the high resolution frequency estimation can be obtained using a single vector sensor.
如果将空间的位移变成时间的延迟，单个矢量传感器可以实现高分辨率的频率估计。

2.In order to yield high resolution, the high-order autocorrelation matrix is used, the number of the operations for the estimation of frequency and power is tremendous.
为了达到高分辨率而采用高阶相关矩阵，谱估计的运算量十分大。
