摘　　要：模糊相位差定位是当前无源定位体系中的一个热点问题。传统LBI解模糊算法设备需要量大、信号处理复杂。利用卫星测量获得的"模糊"相位差与目标位置始终表现出最强的相关性原理,提出了基于运动学原理的LBI解模糊算法。仿真实验表明:在满足30°天线覆盖范围要求下,该算法收敛速度快,定位精度高,设备需求少,具有较强的工程可实现性。Fuzzy phase differences location is a hot spot of the passive location system currently. Traditional LBI fuzzy algorithms need a large amount of the devices and need to handle complex signals. Used the principle that ＂fuzzy＂ phase differences obtained by the satellite were always exhibit the strongest correlation, method of LBI fuzzy solution based on the kinematic principle was put forword. The results of simulation showed that with antenna coverage at 30 degrees, the algorithm had a fast convergence speed, high positioning accuracy and a few devices so that it could be realized by the engineering.
