Maneuvering target-bearing tracking is one of the most attractive research areas in underwater acoustic signal processing. The horizontal circular array is isotropic and exhibit the same beamforming effect in all bearings, which is better than the linear array under the same aperture. This paper presents an experiment on Qiandao Lake using a horizontal circular array and an unscented Kalman filter to solve the underwater maneuvering target-bearing tracking problem. Compared with the conventional beamforming method, it was verified that the addition of prior models can improve the performance of maneuvering target-bearing tracking.
