Abstract
A method and apparatus for detecting radar signals in single and multiple (extension) channel wireless network frequencies uses spectral and DC analysis. Spectral images produced through a Fast Fourier transform may be captured and analyzed to determine if any radar signals may be present within the selected wireless network frequencies. A plurality of spectral images may also be analyzed to determine if frequency shifting radar signals are present as well. DC analysis of the power contained at the wireless carrier frequencies may detect radar signals that may be centered near those frequencies.
