In recent years, microbubble contrast agents have become a potential adjunct in Doppler ultrasound diagnosis. In this paper, we show that volume scattering makes the effective band in Doppler spectrum shift downward after injection of microbubbles. Because the insonified volume comprises a collection of distributed microbubbles, the statistical properties(More)
A velocity compensation method based on extended Keystone transform (EKT) for detecting high speed moving target with modulated stepped-frequency radar is presented in this paper. The range migration of target is corrected by EKT and KT, and the range-Doppler coupling and range-profile distortion are compensated by means of processing via Doppler channel(More)
