This paper presents a highly integrated ultrasonic phased array inspection system based on AD9273. The system is designed based on traditional ultrasound phased array inspection system. In the system, some new and highly integrated chips, such as AD9273 and HV748, are used to complete 32-channel high-voltage transmitter and receiver acquisition circuit, FPGA subsystem and ARM platform are used to constitute the core of digital signal processing part, and digital quadrature envelope detector is used to complete the receiver beamforming. The system meets the real-time, high-speed requirements of detection systems. Significant improvement appears in the systems level of miniaturization and digitization. This solution provides the basis for Portable ultrasonic phased array inspection system.
