A Quasi-Vandermonde Determinant and its Application to DOA Estimation of Coherent Sources

给出了准范德蒙行列式的定义、求值表达式及其证明，并对估计到达波方向的Ｅａｕａｔｉｏｎ方法进行了理论证明。

In this paper, a Quasi-Vandermonde (QV) determinant is defined and its recursive valued formnula is proposed. Furthermore, Equation Method, an application of QV determinant to DOA estimation, is given and proved.
