摘要
针对测时差非线性定位算法定位模糊、计算量大等问题 ,提出了一种线性测时差的求解算法。其实质是把非线性定位算法中的非线性项看作一个未知变量 ,通过增加一个时间差测量值 ,把实位的非线性方程变为线性方程求解。并具体就基本的测时差定位法和具有冗余数据的测时差定位法两种情况 ,给出线性测时差定位公式 ,并进行了精度分析。
To reduce the amount of computation and the location blur of nonlinear algorithm, it regards the nonlinear component of nonlinear algorithm as a unknown variable of linear algorithm. A linear algorithm of time-difference of arrival measurements is investigated based on the normal location of time-difference of arrival measurements and the redundancy location of time-difference of arrival measurements. In the end, the precision of location algorithm is analyzed.
