(some col.) + 1 online resource In this project, development of fish finding sonar using a Field Programmable Gate Array (FPGA) has been examined. Designing a transmitter circuit and receiver circuit and design a sonar sensor module and ensure it is waterproof has been discussed. Various methods were tried and tested in order to make a better transmitting and receiving circuits with better amplification. In order to get a proper signal from the speaker and to make it properly waterproof, several methods were tried and tested. By using those hardware parts, a fish was detected and the distance to the fish displayed. A capstone project report submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Engineering Electronics Engineering, School of Engineering and Technology Capstone Project (B.Sc.)-Asian Institute of Technology, 2017 Sonar in fishing Field programmable gate arrays Programming Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B14230 http://203.159.5.9/ait-thesis/detail.php?q=B14230 191030 20260818090836.0
