Underwater vertical x-z plane localization with Multi-node Omni-directional Antennas simulated gain pattern

In this paper, underwater vertical plane (x-z plane)´s localization using EM wave is derived by Multi-fixed Antenna nodes gain pattern. Each antenna has irregular EM wave gain pattern. Since EM wave is too difficult to use in vertical localization. However, this paper shows a possibility of vertical localization using EM wave. First this paper choose specific antenna which called Omni-directional antenna and find a method for estimate initial position by triangulation. In addition, the Newton-Rapthon method used to find final position. Finally the simulation of vertical area is realized with multi-fixed nodes environment by computational approach.
