摘要
舰船磁场信号空间衰减快,且易被近场环境磁场干扰,这就要求有更高精度的微弱磁场探测系统。本文基于自振荡离散波束铯蒸气型CS-133光泵探头,设计了一款高精度的磁场探测系统,对系统的信号处理电路进行了设计和研究,并对光泵探头的探测原理和参数进行了分析和计算。测试表明,本系统具有高精度的磁场分辨率和较好的远场微弱磁信号检测能力。
The ship magnetic field signal space is quickly decayed and can be easily disturbed by near field environmental magnetic field, which requiresa weak magnetic field detection system with higher precision. Based on the self oscillation of discrete beam of cesium vapor CS-133 optical pump probe, this paper designs a high precision magnetic field detecting system, designs and researches the signal processing circuit of the system, and analyzes and calculates the detection principle and the parameters of the optical pump probe. The result sshow that this system has high precision magnetic field and good signal detection capability of far-field weak magnetic.
