Parameters Estimation of Ultrasonic Echo by Levenberg-Marquardt Algorithm

摘要：

A heuristic method of using Levenberg-Marquardt algorithm with super global performance to meliorate the singular iterative matrix of Gauss-Newton was put forward to overcome the harsh terms of initial value in Gauss-Newton algorithm. Computer simulation and experimental results were performed to verify the performance of the proposed method. This method of modeling and estimation leads to the quantitative evaluation of ultrasonic signals linked to the physical properties of targets and the propagation path.
