An Energy-concentrated Wavelet Transform for Time Frequency Analysis of Transient Signals [PDF]
arXiv, 2022 Transient signals are often composed of a series of modes that have multivalued time-dependent instantaneous frequency (IF), which brings challenges to the development of signal processing technology. Fortunately, the group delay (GD) of such signal can be well expressed as a single valued function of frequency.

Detection of Compressed Pulse Signals by Processing Energy Distribution Ratio [PDF]
Japanese Journal of Applied Physics, 1992 A compressed pulse signal obtained when a linear FM signal has gone through a matched filter has a typical waveform of a sampling function. This means that energy of a compressed pulse signal is concentrated near its center peak as is the case with the sampling function.
