All-purpose and plug-in power-law detectors for transient signals

Recently, a power-law statistic operating on discrete Fourier transform (DFT) data has emerged as a basis for a remarkably robust detector of transient signals having unknown structure, location, and strength. In this paper, we offer a number of improvements to Nuttall’s original power-law detector. Specifically, the power-law detector requires that its data be prenormalized and spectrally white; a constant false-alarm rate (CFAR) and selfwhitening version is developed and analyzed. Further, it… CONTINUE READING
