给出了运动辐射源多站三维时差定位的算法模型和定位误差模型。并针对4种站址布局情况，初步计算了定位精度与布站的关系，给出了各种定位精度曲线仿真结果。

The position location models of 3 D moving emitter using time difference of arrival in multisites systems and location error models are discussed. Being aimed at the four type disposition, the correlation of the location error with radar arragement are preliminarily calculated, the curves as well as the simulation results are also given.
