Layout optimization of bionic lateral line sensor array based on Bayesian estimation

When underwater detection is carried out, the bionic side-line sensor array will be affected by obstacles in the water. At present, most of the bionic side-line sensor arrays adopt the uniform distribution layout, which has certain limitations. The layout optimization of the bionic side-line sensor array has become one of the difficult problems to be solved. In this paper, aiming at the layout problem of the bionic side-line sensor, an optimization layout of the bionic side-line sensor array based on Bayesian estimation is proposed. Based on the theory of Bayesian estimation, the objective function is derived based on the information gain of the airfoil carrier in the flow field environment. The objective is searched under the framework of heuristic algorithm, and the flow velocity sensor array is optimized. The results show that the flow velocity sensors are mostly distributed in the head of the airfoil carrier.
