| 摘 要： | 针对利用舰船磁场定位海底矢量传感器的方法中存在的不足,提出一种采用海面的通电线圈作为磁偶极子源来定位海底传感器位置的方法。该方法将载流线圈的磁感应强度用多个磁偶极子来等效,在综合水深测量值和磁感应强度矢量测量值的基础上将位置确定问题转换成以传感器位置为参变量的非线性无约束优化问题,并采用L-M算法求解了该问题的加权最小二乘解,实现了传感器定位。模型实验和仿真实验的结果表明:该方法能够实现海底矢量磁传感器的有效定位,且当风浪引起线圈平面与地磁坐标系的偏转角小于5°时,该方法仍然适用。

| Abstract: | Aming at the shortages of the method that using ship's magnetic field to locate the underwater vector-magnetometers,a method on determination of the position of the sensors by using a current coils in the offing,which was taken as magnetic dipole sources.The magnetic flux density of the coils was equivalent to several magnetic dipoles.On the basis of integrating the measuring values of water depth and magnetic flux density,the position determination problem was converted to a non-linear unconstrained optimi... |
