Based on the problem of the difficulty to set up the precise models for the information fuse method which bases on the Kalman filters, a new method based on the autoregression (AR) model is put forward in this paper. This method is one of the time series analysis methods, which uses the temporal correlation between the errors data to set up the AR model, and then the estimation results are utilized...
In order to achieve the unified measurement of the air velocity from subsonic to supersonic circumstance, an analytical method referred to as the equivalent acoustic source, which was only suitable for the analysis of supersonic air current before, is extended to the subsonic case. Systematic analysis demonstrates the essential difference of the air current property between subsonic and supersonic...
