Inverse synthetic aperture radar (ISAR) imaging at low SNR ratio is not resolved completely. The SNR increases in time-frequency domain over the one in the time or the frequency domain alone both theoretically and numerically. This shows advantage of time-frequency analysis technique for ISAR imaging at low SNR. The reassigned Gabor spectrogram time-frequency distribution is proposed for ISAR imaging at low SNR. Finally, the real data demonstrated the validity of the method proposed.
