一种降低电场辐射发射测试测量误差的方法

A Method of Reducing Measure Error of Electromagnetic Emission Measurement

随着电磁兼容试验技术的发展,测量误差已经成为评估测试是否符合相应标准的关键性指标。为了降低军用设备的电场辐射发射测试的测量误差,本文对误差偏高问题的原因进行了分析,并针对要因提出在天线周围放置吸波材料及对测试结果进行校准的方法,使得测量误差大大降低,从而保证了军用设备的电场辐射发射测试数据的准确性和可靠性。

Along with the development of EMC experimentation technology,measure error becomes a key guide line of evaluating whether measuring accords with the relevant standard.To reduce error of the electromagnetic emission measurement,the reasons for high error and a method of setting up radar absorbing materials around the antenna is analyzed and calibrating of test results is put forward.By this method,the measurement error can be greatly reduced,and the veracity and reliability of the electromagnetic emission measurement is guaranteed.
