This paper proposed short Fourier transformSTFTtime-frequency analysis method of fractional lower-order alpha stable distribution based on conventional STFT. Simulations show that the proposed method has more excellent performance than conventional STFT in time-frequency analyzing of alpha stable distribution process and is a new one in time-frequency domain research of alpha stable distribution. %K alpha stable distribution %K fractional lower-order %K short Fourier transform(STFT) %K time-frequency analysis
