    Analysis of the influence of ultrasonic transducer on pulse compression performance of chirp signal

    In this paper, the effects of ultrasonic transducer on the signal-to-noise ratio and axial resolution of coded signals after compression are studied under different coding bandwidths. The pulse-compressed time domain peak is converted into the form of frequency domain integral, and the pulse compression signal-to-noise ratio formula considering the influence of the transducer is obtained. Taking the chirp signal as an example,the simulation and experimental results show that the signal-to-noise ratio gain of the coded excitation relative to the square wave excitation increases with the decrease of the coding bandwidth. Because of the limitation of transducer bandwidth, the axial resolution of coded excitation method decreases first and then stabilizes with the increase of coding bandwidth. The research in this paper provides a reference for the application of coded excitation method in the background of ultrasonic detection.
