摘要：
The Linear Frequency-Modulated signal (LFM) has been used widely in radar signals. Using the characteristics of the linear frequency-modulated signal in fractional domain, three kinds of algorithms based on fractional domain have been put forward, that is, the maximum value detection, the energy concentration detection and the signal kurtosis detection. What’s more, the detection performance of each algorithm has been analyzed qualitatively.
