چکیده    In this paper, after defining pure proportional navigation guidance in the 3-dimensional state from a new point of view, range estimation for passive homing missiles is explained. modeling has been performed by using line of sight coordinates with a particular definition. to obtain convergent estimates of those state variables involved particularly in range channel and unavailable from ir trackers, nonlinear filters such as sequential u-d extended kalman filter and unscented kalman filter in modified spherical coordinate combined with a modified proportional navigation guidance law are proposed. simulation results indicate that the proposed tracking filters in conjunction with the dual guidance law are able to provide the convergence of the range estimate for both maneuvering and non-maneuvering targets.
