An algorithm to track multiple sharply maneuvering targets without prior knowledge about new target birth is pro-posed.These targets are capable of achieving sharp maneuvers within a short period of time,such as drones and agile missiles.The probability hypothesis density(PHD)filter,which propa-gates only the first-order statistical moment of the full target posterior,has been shown to be a computationally efficient solu-tion to multitarget tracking problems.However,the standard PHD filter operates on the single dynamic model and requires prior information about target birth distribution,which leads to many limitations in terms of practical applications.In this paper,we introduce a nonzero mean,white noise turn rate dynamic model and generalize jump Markov systems to multitarget case to accommodate sharply maneuvering dynamics.Moreover,to adaptively estimate newborn targets'information,a measure-ment-driven method based on the recursive random sampling consensus(RANSAC)algorithm is proposed.Simulation results demonstrate that the proposed method achieves significant improvement in tracking multiple sharply maneuvering targets with adaptive birth estimation.
