Ahmed Rebai, Tarek Salhi, Pascal Lautridou, Olivier Ravel

摘要:

基于常用的最小化算法,讨论了超高能宇宙射线引发的空气簇射电波波前曲率的重建问题。我们强调的重要性,引起的收敛过程中的最小化的非线性最小二乘函数,影响退化的解决方案和偏见方面的结果。我们推导出一个简单的方法来获得一个令人满意的估计的排放源的主要点的位置,这减轻了以前遇到的问题。

英文摘要:

Reconstruction of the curvatures of radio wavefronts of air showers initiated by ultra high energy cosmic rays is discussed based on minimization algorithms commonly used. We emphasize the importance of the convergence process induced by the minimization of a non-linear least squares function that affects the results in terms of degeneration of the solutions and bias. We derive a simple method to obtain a satisfactory estimate of the location of the main point of emission source, which mitigates the problems previously encountered.
