Datamissing phenomena may happen in engineering testing due to the mismatch of component parts or breakdown of the testing system. In this paper, a parameter model is proposed to recover the missingdata. Through analyzing the correct data, the structure, the best order and the specific parameters of the model can be determined, and be further tested and optimized, so that the best model can be obtained. Finally, as an example, an AR model is applied to resume the missing data in the testing of an actual flight. The results show that the method is feasible and effective.
