英文摘要Gravitational waves (GWs) from core-collapse supernovae (CCSNe) have been proposed as a means to probe the internal physical properties of supernovae. However, due to their complex time-frequency structure, effectively searching for and extracting GW signals from CCSNe remains an unsolved challenge. In this paper, we apply the improved multisynchrosqueezing transform (IMSST) method to reconstruct simulated GW data based on the advanced LIGO (aLIGO) and Einstein Telescope (ET) detectors. These data are generated by the rotational and neutrino-driven mechanisms, and we use the match score as the criterion for evaluating the quality of the reconstruction. To assess whether the reconstructed waveforms correspond to true GW signals, we calculate the false alarm probability of reconstruction (FAPR). For GW sources located at 10 kpc and data sets where the waveform amplitudes are normalized to 5x10(-21) observed by aLIGO, FAPR are 2.1x10(-2) and 6.2x10(-3), respectively. For GW sources at 100 kpc and with waveform amplitudes normalized to 5x10(-21) observed by ET, FAPR are 1.3x10(-1) and 1.5x10(-2), respectively. When the GW strain reaches 7x10(-21) and the match score threshold is set to 0.75, the IMSST method achieves maximum reconstruction distances of approximately 37 and 317 kpc for aLIGO and ET, respectively. Finally, we compared the performance of IMSST and STFT in waveform reconstruction based on the ET. The results show that the maximum reconstructable distance using STFT is 186 kpc.
