Abstract

The reasonable number of base stations in multiple acoustic array azimuth cross location is studied. In this paper, the maximum likelihood estimation (MLE) algorithm is used to discuss the problem of increasing the number of arrays to improve the positioning accuracy, and the positioning error model is given. The experimental results show that with the increase of the number of base stations, the positioning accuracy will gradually improve, but if there are too many base stations, the improvement of positioning accuracy will gradually slow down.
