Use of fractional autocorrelation in efficient detection of pulse compression radar signals

In the recent past, fractional cross-correlation and autocorrelation operations associated with the fractional Fourier transform (FrFT) have been formulated. A detection statistic based on fractional autocorrelation has been employed for detection of linear frequency modulated (LFM) signals. In this paper, we extend the utility of the detection statistic based on fractional autocorrelation for detection of pulse compression radar waveforms. In particular, we consider the step LFM signal and the waveforms of Frank code and P4 code.
