在建立优化目标函数过程中采用座标形式为未知量，从而使计算公式更为简单。
For establishing the optimal target function we use the coordinate values as the unknown variables and thus the calculating formulas are further simplified.
针对相干信号源分布式目标，在具体的空间信号分布函数形式未知的情况下，提出了一种基于盲辨识的分布式目标波达方向（DOA）估计方法。
This paper proposes a blind identification approach to direction of arrival estimation of coherently distributed sources without knowing the accurate function forms of the angular signal density.
