3维脉冲电场测试中扰动电场效应分析
|
摘要
为了解决脉冲电场测试时,传感器对被测电场的扰动问题,以三棱锥形3维脉冲电场传感器为研究对象,利用矩量法分析了脉冲电场测试时的电场扰动因素。在CST2011中具体分析了传感器探头和天线尺寸对被测电场的影响,并从电路的角度分析了传感器3维天线的极间耦合。根据被测电场与传感器输出电压间的线性关系,构造了影响因子矩阵对扰动电场进行了校正。结果表明:校正后的电场误差率<5%,3维天线间的最大耦合系数也由原来的11%降低到4.3%。
In order to solve the distortion in pulse electric field tests which is brought by the sensor, taking a triangular pyramid shape three-dimensional pulse electric field sensor as a research object, we adopted the method of moment to analyze electric field distortion factors in the pulse electric field tests. The effects to E-field which is caused by the sensor probe and the antenna were analyzed in detail in CST2011, and then from the perspective of the circuit, the 3-D antenna coupling was analyzed. According to the relationship between the sensor output voltage and the measured electric field, the impact factor matrix is constructed to adjust the distortion electric field. The results show that the error of the E-field test after adjustment is less than 5%, and the maximum coupling coefficient will decrease from 11% to 4.3%.
