In summary, our work makes three key contributions. First, we introduced a blind source separation-based approach to isolate single radar signals from aliased environments, effectively addressing the challenge of signal aliasing. Second, we proposed an innovative waveform shaping method using the floating threshold of the Hilbert envelope, which enables precise extraction of pulse arrival and end times. Third, we demonstrated through simulations that our method achieves high accuracy in PRI estimation, with similarity coefficients exceeding 0.999 and minimal deviation from true PRI values. These contributions significantly enhance the performance of radar signal parameter estimation and identification analysis.
