基于奇异值分解的潜艇磁场推算

摘要

For the problem that submarine defense against magnetic detection, a high accuracy model extrapolating the magnetic distribution of submarine is established based on the magnetic dipole array model. Singular value decomposition algorithm is proposed for resolving the model, and calculating results derived from the algorithm are compared with the real measured values. Comparison results show that singular value decomposition algorithm is effective in calculating high accuracy submarine magnetic field. Magnetic field of submarine in high altitude based on singular value decomposition algorithm is simulated, and the simulation results can provide technology references for the submarine defense against magnetic detection.%针对潜艇磁性防护,基于磁偶板子阵列模型,建立了潜艇磁性目标高精度磁场计算模型.提出了利用奇异值分解的方法对模型进行求解,利用该求解算法进行了模型计算与实测数据比对,结果表明,该计算方法能够有效适用于计算高精度潜艇磁场.基于奇异分解的方法计算了潜艇高空磁场,计算结果可供潜艇防护磁性探测参考.
