摘要

作者对阵列的互相关矩阵进行了双边变换。结果表明，无论信号的带宽如何，双向相关变换(TCT)都能对到达方向产生无偏估计。并将该方法与相干信号子空间方法的分辨能力进行了比较。新技术的分辨率阈值更小。

A unitary transformation algorithm for wideband array processing

The authors apply a two-sided transformation on the cross-correlation matrices of the array. It is shown that the two-sided correlation transformation (TCT) generates unbiased estimates of the directions of arrival regardless of the bandwidth of the signals. The capability of the method for resolving two closely spaced sources is compared with that of the coherent signal-subspace method. The resolution threshold for the new technique is smaller.<>
