| 摘 要： | 提出了探测噪声相关性的图解法,直观地确定噪声的相关程度;基于统计检验的思想设计零假设,并构造检验统计量,给出了探测相关性的假设检验法。结果表明,图解法和假设检验法均能有效地判断噪声的相关性,实用中可将两种方法相结合,以达到最佳效果。

| Abstract: | In the data processing of kinematic navigation and positioning,the correlation character of observation noise can not be known in advance,which brings out trouble for choosing appropriate method.The graphic method is put forward to determine correlation extent visually.On the basis of statistic test,the null hypothesis and test statistics is designed,with which the hypothesis test method for detecting correlation is derived.The result of calculation shows that both the graphic method and the hypothesis test... |
