Abstract
A method for detecting the presence of a signal in a frequency spectrum is provided. The method includes receiving the frequency spectrum. The power spectral density of the received frequency spectrum is estimated. A plurality of frequency bins are segmented for the frequency spectrum based on the estimated power spectral density. For segments with an estimated power spectral density above a first threshold, a radar spectral signature matching algorithm is applied to detect the presence of the signal and for segments with a power estimate below the first threshold and above a second threshold, additional techniques are applied to detect the presence of the signal.
