The self-sustained oscillations in three-dimensional rectangular cavities are performed in both subsonic and supersonic flow. The pressure signals on cavity wall are analysed by using short time fourier transform (STFT), continuous wavelet transform (CWT) and higherorder spectral (HOS) methods. The results shows the dominant mode switches between the primary Rossiter modes.
