Since the sea echo is one dimensional signal,this paper,based on an arbitrary triangular array,presents that space-time DOA matrix method,which is originally used to estimate two-dimensional angles of arrival under ideal conditions,can be reshaped to be used under amplitude and phase errors.
针对高频地波雷达回波信号是一维信号的特点,构造了任意形状的三角形阵列,将理想情况下用于二维到达角估计的空时DOA矩阵法进行了推广,使其能适用于存在幅相误差的阵列。
补充资料：R阶差数列
相邻两项相减,得到一个新数列,一直如此操作直到得到常数列,减了几次,就称为几阶差数列
