使用二个双曲线(三个接收机)系统能获得2d目标位置，当使用最少三个双曲面(四个接收机)系统能实现完整的3d立体目标定位。

Using two hyperbolas (three receivers) the system can obtain 2d target position, while using at minimum three hyperboloids (four receivers) the system can achieve full 3d target locating.

目标项位置仅影响目标定位时间，目标激活时间不受对象空间排列方式和目标项位置的影响；

Target position only affected the time of target localization in both arrangements. In addition, the time of target activation was not affected by the arrangement of objects and the target location.
