Design of the Control Circuit Based on FPGA for the Underwater Trash Detection System Guoku Zhaoa, Qi Zhangb Information Science and Technology College, Dalian Maritime University, Dalian, Liaoning, 116026, China azhaogk@yeah.net, bzhqi88@hotmail.com Keywords: Underwater Trash; Ultrasonic Detection; FPGA; Control Circuit Abstract.
In order to determine the distance and material of target, the amplitude of echo wave also need to be extracted, and FPGA is employed to control high-speed AD and process data.
Then this information is sent into host machine, where appropriate algorithm is used to determine the material and location of target.
