Disclosed is an ultrasound imaging system based on a multi-stage pulse compression and multi-stage time delaying scheme. In the ultrasound imaging system, a transducer array is grouped into a predetermined number of transducer groups, and the grouped ultrasound signals are processed hierarchically via multi-stage pulse compression and multi-stage time delaying operations so that a finely receive-focused ultrasound signal can be obtained.
