摘要
为了提高模拟海上目标磁场的效果,从常规磁场反演的方法出发,进一步考虑了目标运动状态下磁场的梯度特性,提出了基于运动特性的海上目标磁场模拟的数学模型。该方法在常规方法只考虑磁场分布规律的基础上,增加了目标磁场在前进方向下的磁场梯度因素,使模拟的方式有了改进,计算速度较快,能够较好反映目标空间磁场的分布,同时更好地拟合目标磁场梯度特性。实验结果表明,利用单轴可变磁矩磁体阵列能够对目标磁场进行有效拟合,且易于在实际工程中实现。该方法精度高、误差小,能保持较高的稳定性,满足舰船磁场模拟的应用需要。
In order to improve the simulating effect of offshore target magnetic field,starting with the conventional method of the magnetic field inversion,considering the gradient characteristics of the magnetic field under the moving state of the target,a mathematical magnetic field of offshore target simulating model based on the moving characteristics was put forward.Based on the conventional method only considering the distribution law of magnetic field,this method increased the magnetic field gradient factor of the target magnetic field in the forward direction,so that the simulation method improved to a certain extent,and the calculation speed was relatively fast.It could better reflect the distribution of the target space magnetic field and better fit the target magnetic field gradient characteristics.Through sufficient theoretical analysis and test of measured data,this paper proved the effectiveness of the method,and the comprehensive simulation effect was better than the conventional method.The experimental results showed that the target magnetic field could be fitted effectively by using the single axis variable magnetic moment magnet array,and it was easy to be realized in practical engineering.
