Abstract

The main work of this paper is proposed an indoor underwater target positioning system and an improved positioning algorithm. The principle of the system is based on the underwater acoustic positioning method for marine positioning. In addition, the structure of the system and the positioning algorithm are improved for the indoor underwater fixed target. The system is based on the short-baseline principle, combined with an ultrasonic transducer, three hydrophones, and a water depth meter to compose an improved short-baseline array, which is used to locate the underwater target. And the artificial bee colony algorithm is used to deal with the distance information. Then the nonlinear optimization problem is solved, and the positioning accuracy of the system is improved. In this paper, the hardware structure, the positioning principle and the positioning algorithm are discussed. The experimental results show that the underwater target positioning system has the advantages of high precision and high stability, and the performance of the algorithm is obviously better than that of other algorithms.
