摘要：
We present a novel ultrasound echo identification technique based on the Singular Value Decomposition of Cross Wigner-Ville Distribution. The theoretical background is presented and followed with detailed explanation of each stage of the signal identification algorithm. We then apply this new echo separation method on asymmetric simulated ultrasound signals. The extracted echo time locations are in good agreement with the actual values.
