| 摘 要： | 车辆及舰船的磁场是超低频交变弱磁场。测量车辆和舰船的近场磁场分布是研究车辆或舰船磁场特征的基础。介绍了将频域数字反卷积算法应用到交变弱磁场测量，用软件积分取代模拟积分器，不但简化了磁场测量仪器的硬件，同时用系统的冲激响应修正了系统的固有误差。基于此原理研制的车辆磁场测量系统验证了这种测量方法的可行性与准确性。

| Abstract: | Magnetic field of ground vehicles and warships is ultra low frequency, alternate and feeble. Magnetic patterns from a moving target provide the basic for researching the character a moving target. In this paper, a measurement method of target magnetic field is discussed based on digital deconvolution in frequency domain. The hardware of the instrument is replaced by software. The inherent error of the system is corrected by the impulse response. Numerical simulations validate the theoretical results and show that the measurement system has an accuracy very close to the fact. |
