A New Robust Method for TDOA Location
-
摘要: 該文提出了一種利用TDOA進(jìn)行定位的新算法，它利用了有關(guān)相對量測誤差上限和站址擾動上限的先驗知識基礎(chǔ)上，對偽線性TDOA方程組進(jìn)行求解，其算法較為穩(wěn)定，通過仿真發(fā)現(xiàn)可知該算法有較好的性能，在定位精度上比傳統(tǒng)定位方法有所提高。

Abstract: A new robust method about location on TDOA is proposed in this paper. It use the known TDOAs variance bound and the error bound of the radars position, to solve the psdolinear equations about TDOA, the algorithm is robust, and its performance is better and have a higher location precision than the others. -
