基于微分进化算法的磁性目标参数估计方法

根据磁场数据来获得磁性目标参数相关信息的方法称为磁探测技术，其在民用和军用领域都有着重要的应用价值。以磁性探潜为背景，首先基于磁场采集数据将磁性目标参数估计问题简化为一个非线性数学模型，进而选择简单有效的微分进化算法求解上述数学模型，以实现磁性目标磁矩和位置参数的估计，并通过仿真试验对方法有效性进行了检验。仿真计算结果表明，该方法能够准确、快速地优化出磁性目标三分量磁矩和空间位置坐标参数，具有一定的实用意义。

Parameter Estimation Method of Magnetic Targets Based on Differential Evolution Algorithm

The information of magnetic targets usually can be obtained based on their measured magnetic field,which is always called magnetic anomaly detection.Magnetic anomaly detection is very useful not only in civil engineering area,but also in military engineering area.Take submarine detection for application background,based on measured magnetic field,the parameters estimation of magnetic targets is reduced to nonlinear mathematical model.To obtain the magnetic moment vector and location,the simple and effective...
