一种无须先验信息的多基站冗余信息法定位技术
摘要：
本发明属于无线定位技术领域，涉及一种无须先验信息的多基站冗余信息法定位技术。本发明是一种新的TDOA定位算法，在传统Fang算法的基础上，增加一组测试基站，通过获取目标冗余信息，把二次双曲面方程组降阶为伪多元一次方程组，求解该方程组，可以唯一确定目标的位置。本发明需要在传统定位测试中增加一个测试基站，获取目标的冗余信息，从而依据冗余信息把二次双曲面方程组降阶为伪多元一次方程组，求解该方程组唯一确定目标的位置。该方法直接排除了解的多值性，从而具有无须任何先验信息，求解速度快，方程组的解具有唯一性，定位精度高等特点。
摘要（英）：

The invention belongs to the technical field of wireless positioning and relates to a multi-station redundant information positioning technology without the need of prior information.The technology is a novel TDOA positioning algorithm, a testing stations is added on the basis of a traditional Fang algorithm, a secondary hyperboloid equation set is descended to a pseudo-multivariate linear equation set by obtaining target redundancy information, the equation set is solved, and a unique target position is determined.According to the technology, one testing station is added to traditional positioning testing, the target redundancy information is obtained, accordingly the secondary hyperboloid equation set is descended to the pseudo-multivariate linear equation set according to the redundancy information, and the unique target position is determined by solving the equation set.According to the method, multi-valuedness of a solution is directly excluded, no prior information is needed, solving speed is high, and the solution of the equation set has the advantages of being unique, high in positioning precision and the like.
