Design of Compact Mechanical Imaging Sonar Circuit

The ocean has an important military position and significance in today's world, and the demand for underwater equipment such as imaging sonar has increased significantly in both civil and military fields. Simultaneously, The author redeveloped a new generation of mechanical scanning imaging sonar TKIS-III , it was developed to meet the requirements of 100% localization of troops and related units in the military field, as well as in-situ replacement of foreign sonar products. This paper describes the design of the mechanical scanning imaging sonar TKIS-III’s power module, analog receiving module, and high-speed A/D conversion module. Finally, indoor and outdoor open water experiments are conducted to validate requirements such as collocated product replacement. The experimental results show that the mechanical scanning imaging sonar TKIS-III meets the replacement requirements while also having lower power consumption and a more stable operation.
