Flutter mode parameters identification plays an important role in flight flutter test. A method is introduced to analyze the impulse excitation signal of Flight Flutter Test. The improved spatial correlation filtering algorithm is used to reduce the noise of the impulse respond signal and improve the estimating precision of frequency response function. The orthogonal polynomial subsection fitting is used during model parameters identification, which helps to achieve estimating the flutter mode parameters。
