摘要

本文对基于单个运动标量磁强计和基于两个运动标量磁强计的磁定位问题分别进行了详细研究

指出用单个运动标量磁强计不能完全确定出目标的位置参数

并给出了一种通用的磁定位方法.该方法先用改进的进化策略方法得到粗值

然后用单纯形法获得精确值.仿真结果表明该方法是切实有效的

而且定位范围大;由于它不需要事先假定磁性目标的磁矩已知

因而是实用的.另外

对该方法稍做修改后

还可将其直接用到基于矢量磁强计的磁定位问题中.

Abstract

By studying the problems of localizing magnetic target based on single motion scalar magnetometer and based on two motion scalar magnetometers in detail

the authors indicate that magnetic target's position parameters can not be completely ensured by adopting single motion scalar magnetometer

and present a universal method of localizing magnetic target.The method first searches position parameters in the rough by adopting modified evolution strategy and then finds precision parameters by using simplex method.Testing experiment results indicate the effectivity and large localization area of the method.Since the method need not know magnetic moment in advance

it is practical.In addition

the method can be directly applied to solve the problem of localizing magnetic target based on vector magnetometer after a few modifications.
