基于MQP模型的电离图参数反演解析算法研究

针对现今普遍采用的偏导迭代电离图反演算法存在的求解依赖于初值选择的不足,给出了一种初值选择准则,保证了该算法的收敛性。同时,利用该准则,以及在对电离图虚高表达式进行合理近似的基础上,提出了一种新的电离图参数反演算法,该方法实现电离图参数反演的解析计算,较偏导迭代法计算量大大减少,更好满足工程实时性要求。

An Analytic Algorithm on Inversion of Ionograms Parameters Based on MQP Model

The algorithm of partial derivative iteration is often used to inverse the parameters of lonograms.But the accuracy of this inversion results are depended on the selection of initial values.So a criterion for the selection of the initial value is proposed to solve this problem.Meanwhile,using this criterion,and the expressions of ionograms virtual high,based on a reasonable approximation, a new inversion algorithm on the ionograms＇ parameters is presented.This method may calculate the ionogram＇s parameters with analytical formula,which makes the calculation greatly reduced compared with the partial derivative iteration method.It will better meet engineering needs in real time.
