基于逐步回归法的潜艇高空磁场仿真

应用目前磁场换算中较多使用的磁荷模拟法对潜艇高空磁场进行了仿真,为了尽量减少磁荷的位置及大小受人为经验的影响,且提高换算精度,采用逐步回归法对各模拟磁荷的磁矩进行筛选,最后对潜艇高空磁场进行了计算机仿真.仿真结果表明,该方法精度比较高,而且模型的稳定性好,对实际防空中磁探具有重要的意义.

Simulation for magnetic field of submarine in high altitude based on stepwise regression technique

In order to evaluate the ability of submarine defense against the air magnetic-detecting,the method of magnetic-granule imitation is applied to simulate the magnetic field of submarinein the air.But the difficulty of the method of magnetic-granule imitation lies in the position and sizes of the magnetic-granule is greatly influenced by the artificial experience.As toreducethis kind of influence as muchas possible,and improve the precision of conversion,the stepwise regression techniqueis applied to filtrate the magnetic-quadrature of every magnetic-granule.In the end,the magnetic field of submarine in high altitudeis simulated by computer,and the result of simulation shows that the method has high precision and good stability.It has great importance to the defense against the air magnetic-detecting.
