摘要

B-dot传感器因其频带宽, 体积小以及良好的稳定性而广泛应用于电磁脉冲(EMP)测量。任何理论模型与实际情况之间都存在差异, 因此B-dot传感器必须在实验室环境下进行标定。针对传统的时域标定方法存在的弊端, 提出一种基于输出误差(OE)模型的频域标定方法。该方法利用单输入单输出的OE模型传递函数来表征B-dot传感器的频响特性, 然后通过部分线性回归求得传感器实际工作的频率范围的灵敏度系数。经验证, 该方法能够有效避免因阻抗突变引起的过冲或振铃现象对标定精度的影响。

Abstract

B-dot sensors are widely used in electromagnetic pulse (EMP) measurements due to their wide frequency band, small size, and good stability. There is a difference between any theoretical model and the actual situation, thus the B-dot sensor must be calibrated under the laboratory environment. Aiming at the shortcomings of traditional time-domain calibration methods, this paper proposes a frequency-domain calibration method based on OE model. The method uses the OE model transfer function of single input and single output to characterize the frequency response characteristics of the B-dot sensor, and then obtains the sensitivity coefficient of the frequency range in which the sensor actually works by partial linear regression. According to verification experiment, it can be determined that this method can effectively avoid the influence on calibration accuracy of overshoot or ringing caused by impedance mutation.
