A Novel Maneuvering Target Tracking Algorithm with Extended Measurement and State Vector

Aiming at the practical application of tracking maneuvering underwater-target, the rate measurement gotten by sonar was a relative radial rate, could not be used directly, and the sensor data was color contaminated. A new maneuvering target tracking algorithm with extended measurement vector (i.e. relative radial rate) and extended state vector was proposed in this paper to improve the steady-state estimating accuracy and the constringency rate. Some Monte Carlo simulation results were presented, which showed that there was significant improvement in tracking capability over the measurement conversion method (such as MC method)
