Quadraturephase method is one of the important methods in directional blood flow information detection using Doppler ultrasound techniques.
正交相位法是超声多普勒技术中提取双向性血流信息的一种重要方法。

Finally, some ways of MTI processing are compared in amplitude and phase unbalances of quadrature channels.
最后比较了几种MTI处理方法对正交通道幅相不平衡度的要求。

The system distortion is inevitable in wide-band analog quadrature receiver because of the existing of amplitude and phase errors, the performance of receiver become worse.
