A detecting method for the phasedrift in excited signals based on wavelet packet analysis is presented. This method can detect the transient phasedrift in signals at great level.
提出了一种基于小波包分析的激磁信号相位漂移检测方法，能够以较高的精度检测出相位信号的瞬时漂移。

Operating in bad environments and wide band conditions, the amplitude and phase of monopulse sum and difference channels may drift severely.
工作在宽频及恶劣环境条件下的单脉冲雷达，和差通道的幅度和相位会发生严重漂移。

This approach the problem of conquers phase excursion and frequency drift that anciently adopts fixed frequency filter and its frame is simple.
