【Abstract】 The utilization of extended Kalman filters in cartesian for bearings-only tracking introduces errors when the observed equation and state equation are linearized. It thus causes the estimates to deviate from the real parameters while the filter works for a long time.In this paper,a modified Kalman filter with an attenuation memory is proposed.The Monte Carlo simulation experiments demonstrate that this filter has improved the convergence of estimated states and its stability.更多还原
