AI Technical Summary

Problems solved by technology

At present, in the aspect of ultrasonic phased array echo signal reception, a partial digital method based on analog and digital circuits is often used, which results in defects such as complex structure of the receiving circuit, large corresponding equipment that is not easy to carry, poor signal anti-interference ability, and difficult system upgrades.

At the same time, due to the use of analog circuits, it is also difficult to realize dynamic and flexible configuration of the relevant modules of the phased array echo signal receiving system

In addition, the signal processing speed, signal receiving accuracy and data bandwidth of the current ultrasonic phased array echo signal receiving system are generally low
