| Abstract: | This paper uses the a priori information to constrain the parameters, establishes a nonlinear inequality constrained adjustment model, and proposes a new ridge estimation algorithm for solving this adjustment model. The computational results of the two ill-posed examples in this paper show that the new ridge estimation algorithm is feasible, and the accuracy of the calculation results is higher than that of ordinary ridge estimation. |
