The Research on the Simulation of Warship Magnetic Localization Based on Genetic Algorithm

Abstract

Along with the thorough study on magnetic localization of warship, the research on the accuracy judgment method of the magnetic localization solution is more and more important. Previously there has been big limitation of the statistical magnetic localization judgment method based on the statistical phenomenon in the online magnetic localization, so it is difficult to achieve. For solving the above problem, by the aid of the entire search ability of the genetic algorithm, when the movement parameter of the target warship is unknown and the magnetic probe has the attitude angles, adopted the mentality of “Position calculation will be the captain as unknown variables, positioning to determine the amount of time is known to act as a criterion” , complete the magnetic localization arithmetic method based on the single rotation elliptic sphere magnetic model, it can complete the localization arithmetic and location solution identify efficiently. The computed result indicated the effect is good. The Magnetic location of warship can be divided into two sub-problems: positioning solution and the correctness determine of the positioning solution. There has been many research results of the magnetic location solution in comparison, the research on the accuracy judgment method of the magnetic location solution is not sufficient. In real time, with the online request, there isn’t many algorithms can achieve magnetic calculation and the correctness determine of the positioning solution.
