中文摘要
      本文推导了协方差矩阵的对称分块表示法。作为这种表示法在控制工程中应用的实例,对B. Friedland的递推滤波中的常值偏差处理法,在一般时变偏差情况下,给出了解析证明。
英文摘要
      The symmetrical partitioning expression of a covariance matrix is derived in this paper. The major result is: The submatrices D1, D2 and D3 of a covariance matrix D=[D1, D2; D2T, D3] must be satisfied by D2=SD3, D1= Dc+SD3ST. This result was applied to prove analytically B. Friedland’s treatment of bias in recursive filtering in time-varying case.
