摘　　要：针对动态测量过程的复杂性以及随机性,提出了基于贝叶斯理论的动态测量误差的建模、预报方法。该方法要求的数据量少,对动态测量误差序列的平稳性没有要求,并且能够充分利用预报过程中的主、客观信息来实时修正模型,提高预报精度。最后,通过Labview仿真验证了基于贝叶斯理论的动态测量误差预报方法具有较高的预报精度。In view of the complexity and randomness of dynamic measurement course, modeling and prediction method for dynamic measurement errors based on Bayes theory is presented. The method requires less data, and the stability of dynamic measurement errors sequence is not required. The method can make full use of the subjective and objective information to correct the model in real time,improves the prediction accuracy. Finally, Labview simulation result proves that the prediction method of dynamic measurement errors based on Bayes theory has better prediction accuracy.
