abstract = "A direction of arrival estimation method based on short time fractional Fourier transform (STFRFT) is proposed for wideband non-stationary radar and communication integration signals based on phase modulation. This algorithm utilizes the aggregation characteristics of integration signals in the fractional Fourier transform domain and the rotation characteristics of fractional Fourier transform (FRFT) to transform wideband non-stationary signals in the original time-frequency domain into narrowband non-stationary signals in the fractional Fourier transform domain, thereby obtaining a time-invariant fractional Fourier transform domain steering vector, and using the MUSIC algorithm for DOA estimation, effectively avoiding the impact of focusing error on the estimation results. The simulation results demonstrate the effectiveness of the proposed algorithm.",
