摘　　要：给出当前MOA的检测方法并指出了不足,在此基础上提出一种基于A/D转换和微机处理的试验方法数字谐波法。针对MOA检测中的干扰方式如系统谐波、PT相移以及数字波形失真提出了相应的抗干扰措施,取得了一定的效果。After reviewing currently available monitoring methods and their disadvantages,a numerical harmonic methods is presented based on A/D conversion and computer processing.Positive result are obtained with introduction of anti-interference measures against interference sources such as system harmonics,phase deviation of PT and digital wave distortion.
