Associated that BAT(Brainpower Antitank) submunition acoustic detection system cannot fix distance,the bearing-only tracking algorithm of maneuvering acoustic target on ground with BAT is presented in this paper. Firstly the direction algorithm of BAT acoustic detection system is analyzed.Secondly the bearing-only tracking algorithm of maneuvering acoustic target on ground is deduced combined with the characteristics of the motion of projectile body.The corresponding formats of bearing-only tracking are separately deduced when acoustic target are stationary,uniform speed running,in uniform acceleration motion and in other higher phase motions.The sufficient conditions of above formats are given in the presence of direction error.Finally the accuracy function of this algorithm is given which can evaluate the accuracy of the algorithm and optimize the tracking path.The theoretical analysis represents that bearing-only tracking can be realized when the BAT is in less phase motion than the maneuvering target.
