Submarine Antenna Performance with Novel Shaped Sandwich-Wall Radome

Radomes are used for external protection of antennas not only for ground applications and air borne weather Radars but also for submarines to protect antennas underwater. For under water applications, Radomes must have high stiffness, better corrosion resistance, high strength to weight ratio and have to withstand high water pressure. In this paper, performance of a Submarine Radome is analyzed with various wall configurations and two different shapes using FEM based tool ANSYS and Siemens NX. A monopole VHF submarine antenna with AT-6000 specifications is simulated with different parameters under two different Radome structures to check the efficiency and performance under high pressure. This article presents a novel shape Radome structure that faces less stress and deformation with the increasing depth under water as compared to a typical barrel shape structure and can operate in high collapse depths under sea water.
