Abstract

In this paper, we introduce a new time-dependent power spectrum, the Gabor spectrogram. Compared to other methods, the Gabor spectrogram is not only easier for balancing crossterm interference, time-frequency resolution, and other useful properties, but it is also amenable to software as well as hardware implementation. Over the last five years, the Gabor spectrogram has been successfully applied in many areas, such as radar and medical images, noise and vibration, and non-destructive testing.
