随着航空磁探技术和信号处理技术的发展,在不久的将来,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,建立了其空中磁场模型。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 aviation magnetic exploration technology and signal processing technology, in the near future, aviation magnetic exploration is likely to have the ability to detect and identify the magnetic field components of a magnetic anomaly signal source. However, in the current magnetic decoy study, Open-type magnetic source can not simulate the submarine airborne magnetic components of each component. In response to this problem, a scheme of three kinds of magnets with two-electrode type bait magnetic source is proposed, and the airborne magnetic field model is established. According to the measured data of a certain submarine model, the optimal parameters of all kinds of magnetic sources were determined by genetic algorithm, and their simulation results, thermal calculation and power calculation were carried out. The results show that the combination of single magnet and two-electrode can better simulate the target submarine under the premise of ensuring the overall structure of the magnetic source relatively simpler than the two-electrode magnetic source and multi-magnet two-electrode combined magnetic source. Magnetic induction intensity of each component, is a better bait magnet source structure.
