仿生地磁导航技术模拟生物感受地磁场的机制进行导航,涉及仿生技术、弱磁检测技术和导航技术等多个领域。实现对生物地磁导航模仿的前提是充分了解生物的磁感受机制,目前被广泛认可的生物磁感受机制主要是磁颗粒机制和自由基对机制,但这两种机制都存在一定的局限性。有研究表明这两种磁感受机制存在某种耦合。基于磁颗粒与自由基对联合机制,设计了一种新的仿生地磁传感器。该传感器通过软磁材料制作的磁棒来模仿生物体内的磁颗粒,并利用高灵敏度磁传感器来模仿自由基对的磁响应,进而实现对地球磁场信息的感知。利用地磁场模拟装置对仿生地磁传感器进行磁场测试,并通过神经网络获得了传感器测量值与地磁参数之间的映射关系,从而验证了仿生地磁传感器对磁偏角和磁倾角检测的可行性。实测结果表明:基于神经网络算法的仿生地磁传感器具有较高的测量精度,通过模拟导航测试也证明了该传感器在地磁导航领域具有良好的发展前景。
