  • A method of position locating and tracking using pilot .sequence transmitted by the single CDMA Base Stations(BS) for 3-D moving targets is presented in this paper. First, based on the fact that the interfering component is different from the signal reflected by the moving target in the Doppler shift and the property of the auto-correlation function of PN sequence, the interfering component is filtered and the Time Difference Of Arrival(TDOA) is estimated. Then, position location is obtained using the method similar to Chan(1994). Finally, considering the fact that the motion of target is linear with constant speed vector in short duration, the accuracy of position location is improved and the velocity of target is estimated. Its effectiveness is verified by the simulation results.
