A New Method of Bearings-Only Target Localization Based on Parameter Transformation

摘要：

Bearings-only target localization problem is a highly non-linear parameter estimation problem.From the theorem of parameters transformation and particle kinematics,a new parameters transformation filter (PTF)for bearings-only (BO) localization of fixed target in two-dimensional space and three dimensions space was proposed in this paper.An invertible mapping function was found,which transformed the nonlinear filtering problem of bearings-only to a linear filtering problem. Simulation results show that it has a lower localization error than the generally used method known as the modified gain extended Kalman filter (MGEKF)in bearings-only localization example.
