ABSTRACT
In ultrasonic phased array nondestructive testing system, CORDIC is used to optimize the algorithm of key function calculation or data processing in ultrasonic phased array instrument. This paper focuses on the research of ultrasonic phased array FPGA signal processing technology based on CORDIC algorithm, focusing on the ultrasonic echo orthogonal demodulation technology, dynamic FIR filtering technology, time gain control technology. It can reduce the hardware complexity of ultrasonic phased array instrument system, speed up the detection speed and improve the detection accuracy. After the system comprehensive test, the ultrasonic phased array system designed in this paper meets the requirements of industrial application.
