航空磁探仪探潜目标磁梯度定位方法

以反潜巡逻机使用光泵式磁探仪为例，提出一种利用航空磁探仪对潜艇进行磁梯度定位的方法。在较详细地分析潜艇的磁场特性，建立磁场模型的基础上，对反潜巡逻机装备磁探仪如何利用磁梯度矢量来探测潜艇和对潜艇进行定位进行分析，建立了相应的模型，并根据航空磁探仪探潜的特点，将航空反潜中潜艇的远场磁信号等效为磁偶极子磁场。结果表明，通过对潜艇位置做的3次跟踪探测，能较准确地定位潜艇的位置。

Magnetic Gradient Target Positioning Method of Airborne MAD Submarine Detection

Taking the patrol aircraft using the airborne MAD for example,the paper put forward a method of magnetic gradient to get the position of the submarine.On the base of analyzing the magnetic field characteristic of the submarine in detail and setting up the magnetic field model,how the patrol aircraft to make use of airborne MAD to survey submarine was analyzed and set up the model,and according to the characteristic of airborne MAD,the paper took far field magnetic signal be equivalent of magnetic dipole mag...
