摘要
在将混合模型引入时域分析并建立表征超声运动检测回波的一般模型的基础上，对特征结构法的运动估计性能进行了仿真．结果表明，该方法在处理由空间部分相关分布的运动散射子所产生的超声血流信号时同样具有高分辨性能．
The technique ofextracting blood flow velocity with high resolution by eigendecom posing echo array w as discussed.By introducing the hybrid m odelin tim e dom ain analysis,the generalized m odelof ultrasound backscattered echoes from blood flow w as put forw ard.The sim ulating experim ent w ith the application of this m odeldem onstrates that the eigendecom posing echo array m ethod is also efficient in processing ultrasound blood flow signals from the partially correlated m oving scatterers.
