| 摘 要： | 提出了一种在球坐标系下的无源时差定位算法,该算法解决了参变量法中难于解决的模糊和无解问题,计算量小,定位结果可信。当布站接近平面时,本算法可独立进行定位,当站址高度差较大时本算法可以与参变量法相配合解决模糊和无解问题,适合于工程应用。

| Abstract: | An algorithm using TDOA in sphere coordinate is proposed to solve the ambiguity and no solution problems of parameter and variable(PV) method.The computation load is small and the result is reliable.When the station distribution is close to plane,the proposed method can locate by itself;when the station height difference is big,the proposed method can cooperate with the PV method,which fits for the application of the engineering. |
