Maneuvering target tracking under non-all measurement information

Aiming at the situation without all measurement information in the airto-air missile guidance,based on the maneuvering target "current" statistical model,this paper is dedicated to the maneuvering target tracking problem under the spiral maneuvering target model.On the basis of the extended Kalman Filter(EKF) and the decaying extended Kalman Filter,this paper makes use of the modified strong tracking filter(STF) to estimate the maneuvering target information without all measurement information.Simulation experiment shows that the modified STF can not only track velocity and distance but also track acceleration with one more Doppler velocity measurement.Simulation results indicate that the modified STF is effective in some degree.
