Target Positioning and Parameter Estimation Based on Magnetic Dipole Model

在分析了目标的磁偶极子模型之后 ,指出该模型是两个函数的组合 ,目标参数包含在两个函数的参数里 .提出了函数组合法 ,能够将这两个函数分离 ,求出目标的位置及磁矩 .进行了仿真计算 .文章进一步分析了函数组合法的实质 。

After analyzing the dipole model of target,this paper points out that the magnetic dipole signal is a combination of two kinds of functions,and the target parameter is contained in the parameter of these functions.It develops the function construction method for breaking the combination of functions into independent parts,thus determines the target location and magnetic moment in a step by step way.Finally simulations results are presented.The paper goes on to explain the mathematical essence of the method of combined functions,thus the method can be further applied to a broader class of problems.
