摘　　要：基于圆概率误差(CEP),研究了时差定位系统的最优布站问题。分析了时差定位系统的交会角与圆概率误差半径的关系方程,通过解算该方程能够快速获得不同圆概率误差半径下的交会角大小。针对最优定位范围及最优布站引导,提出了一种工程化的快速布站方法。该方法有效提升了无源时差定位和平台最优布站效率。The optimum station arrangement in the time difference of arrival(TDOA)location system based on the circular error probable(CEP)is studied.The relation equation between the cut angle and the CEP in TDOA system is analyzed,and the value of optimum cut angle under different CEP is given.Aiming at the optimum location range and station arrangement,an engineering realization method is proposed.The method can improve the efficiency of TDOA location and station arrangement.
