摘要: 衛(wèi)星干擾源定位系統(tǒng)通過測量兩顆衛(wèi)星對干擾源形成的不同時差和頻差完成對未知干擾源的定位,但定位方程為3個非線性方程,難于求解。學者Haworth等人(1995,1997)提出了利用迭代的算法求解;然而該文的實驗結果表明Haworth等人的迭代算法是發(fā)散的。該文通過詳細的推導,指出了Haworth等人迭代算法的失誤,修改了Haworth等人的迭代算法,并通過實驗驗證了修改后的迭代算法的正確性。Abstract: With differential time offset and differential frequency offset, the position of the satellite interference can be located by using two-satellite techniques. The position equations are non-linear and they are very difficult to be solved. Scholar Haworth, et al. presented an iterative algorithm. However, the position results by using their iterative algorithm were non-convergent in the experiment. The formulas given by scholar Haworth, et al. are deduced carefully in this paper and some faults of their iterative algorithm are found. Then the iterative algoritltm presented by scholar Haworth, et al. is amended in this paper and the amendment is backed up with a successful measurement in the experiment.
