利用單基站對三維運動目標定位與跟蹤

Locating and Tracking of 3-D Moving Targets Using Single Base Station

  • 摘要: 該文提出了一種利用單個CDMA基站發(fā)射的導頻序列對三維運動目標進行定位與跟蹤的方法。首先，利用直達干擾信號與目標反射信號的多普勒頻移的不同及偽隨機序列自相關函數(shù)的特點抑制直達分量，估計相對時延；其次，用與Chan(1994)類似的方法初步估計目標位置；最后,根據(jù)目標在短時間內(nèi)的運動可近似為勻速直線運動的特點來改善定位精度，并實現(xiàn)測速。仿真結果證明了該方法的有效性。
    Abstract: 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.
