摘　　要：随着航空磁探技术和信号处理技术的发展,航空磁探很可能具备对磁异常信号源的磁场各分量进行探测识别的能力,而目前的磁诱饵研究中,两电极直开口式磁源无法模拟潜艇的空中磁场各分量。针对此问题,提出了3种磁体与两电极式相组合的诱饵磁源方案,建立了空中磁场模型。针对某型潜艇模型的实测数据,通过遗传算法确定了各类磁源的最优参数,并对它们进行了模拟效果分析、热计算及功率计算。结果表明:与两电极式磁源及多磁体两电极组合式磁源相比,单磁体与两电极式相组合的方案能够在保证磁源整体结构相对简单的前提下较好地模拟目标潜艇的磁感应强度各分量,是较优的诱饵磁源结构。With the development of aeromagnetic detection and signal processing technologies,aeromagnetic detection equipment is highly likely to have the ability to recognize the magnetic field components of the magnetic anomaly source in the near future.However,in the current research on the magnetic decoy,the two-electrode direct opening magnetic-field source cannot simulate the components of the submarine magnetic field in the air.To solve this problem,a decoy magnetic field source scheme combining three types of magnets and the two-electrode magnetic-field source are proposed,and the calculation formulas for the magnetic fields in the air have been modeled.Based on the measured data of a submarine model,the optimal parameters of all kinds of magnetic-field sources are determined by the genetic algorithm.The simulation results are then analyzed,and thermal calculations and power calculations are carried out.A comparison with the two-electrode type,as well as multi-magnet two-electrode magnetic-field sources,the single-magnet two-electrode magnetic-field source is a better structure scheme for the decoy,which can better simulate the components of the magnetic induction intensity of the target submarine when the overall structure of the magnetic-field source is relatively simple.
