Abstract :
For nonuniformly sampled signal, the paper proposed adaptive matching Fourier transform to get the spectrogram. The procedure is presented. And the astringency and the consistency of the transform are verified. The data based on simulated signal and radar signal shows that adaptive matching Fourier transform can get the signal spectrogram with good performance.
