摘要

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

因而可将它扩展到解一类定位和参数估计问题.

Abstract

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.
