摘要
针对于复杂电磁环境下对北斗干扰源的定位需求,提出利用到达时间差TDOA和到达频率差FDOA的协同定位方法,建立干扰源协同定位算法的数学模型,进行迭代求解和结果评估,分析定位算法的克拉美劳下界。仿真结果表明,该方法具有较好的定位精度和算法性能。
Under the complicated electromagnetic environment for positioning requirement of beidou interference sources,a co-location method is proposed based on Time Difference Of Arrival(TDOA)and Frequency Difference Of Arrival(FDOA),and the interference sources of collaborative localization algorithm is modeled mathematically,which is solved iteratively.An assessment on the results is made and Cramer Rao lower bound of the localization algorithm is analyzed.The simulation results demonstrate that the method has better precision and algorithm performance.
