摘要
模糊度整周解检验是评价模糊度解算正确性的关键,决定着最终定位结果的可靠性。对原有的假设检验存在的缺陷和不足进行了分析,提出了一种更可靠的比值(Ratio)检验方法。理论分析和数值试验结果都显示改进的检验方法更能正确评价模糊度整数解解算的正确性。该新检验方法,又提出了一种最终模糊度整数解确定的新方法即模糊度候选值再分析法。实验表明:应用该方法能提高模糊度整数解确定的成功率。
It is very significant to determine whether the integer solution of the phase ambiguity is correct, which assures the reliability of the positioning result. In this paper, a more reliable Ratio test approach is suggested based on the analyzing of the applying hypothesis test. Theory analysis and numerical computation results have showed that the modified test approach is more proper in the reliability verifying of the integer ambiguity than that of applying. For improving the success rate of the resolution of the phase integer ambiguity, a new algorithm is designed called Reanalysis of the Searched Ambiguity Candidates in the paper. Experiments show that this algorithm can select the correct ambiguities from candidates, which can improves the success rate of the resolution of the integer ambiguity obviously.
