Based on tikhonov regularization method and considering sufficiently the practice of geodesy, the main thread of the choice of the regularizer and the determination of the smoothing parameters is grasped and the in-depth research on the ill-posed problems in geodesy is carried out . a framework of the theory and methods of systematically processing the ill-posed problems has been established and tikhonov regularization method has been evolved in this paper 本文基于tikhonov正则化方法和欧吉坤研究员提出的选权拟合的研究思路,充分考虑大地测量实际,抓住正则化矩阵的选取和正则化参数的确定这条主线,对大地测量中的不适定问题进行了深入研究,建立起了一套较系统的不适定问题处理理论及方法的框架,进一步发展了tikhonov正则化方法。
