电磁脉冲微分测量数值积分修正 Electromagnetic Pulse differential measurement numerical integration correction

摘要

电磁脉冲(EMP)探测器测量结果为微分信号的情况下，需要将测量信号进行积分。测量信号中的噪声在数值积分被放大，产生的累积误差会引起波形的严重失真。同时，由于被测信号上升沿与下降沿宽度不一致，测量到的微分信号正、负峰值以及脉冲宽度不对称，采取消除一次趋势项的方法不能完全消除积分信号的线性趋势。本文结合脉冲电磁场的微分测量结果，在分析了误差传递规律和被测信号特征的基础上，应用信号微调的方法对数值积分结果进行修正，修正后的积分结果消除了线性趋势，能够反映出被测信号的基本特征，为高斯脉冲、方波的微分信号的数值积分提供了一种很好的途径。

Abstract

The processing of differential signal is an important task in Electromagnetic Pulse(EMP) measurement. Numerical integration is one of the ways to process the differential data, but the noise accumulation of measurement signal and the characteristics of original waveform will result in serious distortion to the integration waveform. With the EMP measurement data, on the basis of analysis of error transferring rules and the waveform characteristics, the integration waveform correction method based on piecewise adjustment is adopted in the paper. The results indicate that the correction waveforms are properly to eliminate the trend of errors, and the method is helpful in EMP differential measurement.
