Application of Kalman Filter in Passive Target Tracking

The applications of Kalman filter in bistatic passive target tracking systems are discussed.The nonlinear model of bistatic passive tracking systems are discussed first,and then the procedures for extended Kalman filter which applied to such model are analyzed.The accuracy of estimation of different angle between the targets and passive systems are investigated by computer simulations.Simulation results illustrate that the extended kalman filter can achieve accurate parameter estimation.Moreover,the faster the angle between the target and the passive systems changes the smaller error is to be expected.
