摘要
本文讨论舰载无源声纳对运动声源跟踪定位中的病态问题，提出了一种最小二乘的简单修改形式，不增加计算量，就可显著提高估计精度，并证明了这种修改算法理论上的合理性，得出了关于如何减轻病态，提高估计精度的更一般的结论．
The ill-condition in locating and tracking a moving source from the passive sensors on board is discussed-A simple modified form of Least Square without additional computation,which can improve the estimation accuracy evidently, has been discovered by engineers.In this paper the justification of this modified form of least square is proved. Moreover,through the theoretical analysis on the ill-condition of least square, more general results are presented.These results can be used to ease the ill-condition and improve the estimation accuracy.
