提出适用于EMT的基于相位反馈搜索的信号解调方法。这种双模式系统要求数据采集和处理部分同时解调安装在不同角度的检测线圈的实部和虚部信息。
The signal demodulation method based on phase feedback search is proposed for EMT. This dual-mode system requires the data acquisition and processing section to simultaneously demodulate the real and imaginary parts of the detection coil mounted at different angles.
