Direction-finding array layout optimization technology based on artificial intelligence algorithm

In this paper, aiming at the problem of element arrangement of DF antenna array in reconnaissance equipment, combined with the characteristics of high-speed movement and shape and size of the device, an optimization method of direction finding array arrangement is proposed. According to the relationship between the direction finding accuracy and the position parameters of the array elements, the antenna array layout problem of the direction finding device is transformed into a convex optimization problem about the optimization of the array element position parameters. On the basis of modeling, the weight of convex optimization problem is set according to the requirements of technical scheme, and the most reasonable antenna layout position is obtained through optimization. The optimization method can make the direction finding accuracy close to the lower limit of accuracy as far as possible, and it does not need complicated experimental work. It is easy to realize and is suitable for engineering application.
