摘要
基于相关权逆阵和二次差分矩阵的对应关系,利用Delta函数的性质,推导了时序差分组合的相关权矩阵公式,并利用Matlab对解析表达式进行了数值验算。该公式可以直观地反映出差分组合观测量的统计相关信息。
An analytical expression is presented for the weighting matrix of a set of time-differeneial measurements based on the close relationship between eovarianee matrix and seeond-differeneial matrix as well as the special property of Delta functions. Simulation by using Matlab verified the formula, which has the merits of directly reflecting the stochastic information of time-differeneial measurements.
