摘要：
In order to meet the requirement of underwater ultrasonic phased array imaging system, a high-precision underwater ultrasonic phased array transmitting system is designed and implemented. The system adopts FPGA as the control core, and realizes the high precision phase controlled delay of 0.5ns. At the same time, a driving circuit is built with a high speed triode to realize phase control emission, level conversion and power amplification of the 16 way ultrasonic trigger signal. The system can achieve high-precision focusing emission and deflection emission by setting various phase controlled delay. The actual test results show that the system realizes triggering of ultrasonic phased array transducer, and the phase delay accuracy and low hardware complexity, driving ability, stable and reliable, can provide a good foundation for improving the imaging quality of phased array system.
