Numerical Study of Underwater Inflatable Co-Prime Sonar Array (UICSA)

Abstract

Underwater Inflatable Co-Prime Sonar Array (UICSA) is a compact sonar array assembly that can be deployed in the ocean then morph into a predetermined length to work. As a sonar array, it is critical to reduce the structural deflection and maintain sensor spacing under external forces like ocean currents. The array, like the mooring system, is affected by ocean currents. In this paper, we conduct the numerical study of the morphed UICSA made of different materials in different current conditions using OrcaFlex. The results can evaluate the performance of different UICSA systems and determine the optimal UICSA design.
