Computing Method of Lower Half Space of Underwater Targets Magnetic Anomaly

针对水中目标空中磁场测量困难导致无法对其上半空间磁场量级进行准确评价的问题,提出了基于下半空间测量水中目标磁异常计算方法。该方法利用成熟的目标下半空间磁场测量技术,获取下半空间磁场数据,通过混合阵列模型反演建模,延拓算法进行换算来获得目标上半空间的磁场分布特性。仿真计算结果表明,测量误差优于12%,该方法可用于水中磁性目标的空中磁场量级评价。

It is difficult to measure underwater target magnetic field,which made the upper half of its space evaluation was not accuratel.A new method of magnetic anomaly detector of underwater targets measured from the lower half space was given.The method used sophisticated target under half-space magnetic field measurement method to get the under half-space field data.It was carried out by mixing an array of models in terms of distribution to get the half-space magnetic field on the target.Simulation results verified by laboratory tests,the measurement error was better than 12%,the method could be used to evaluate the magnetic field of the order of air.
