| Abstract: | Disturbing of the color noise and level setting of detecting signal have shaping influence for signal reconnaissance. This paper discusses how to extract the color noise edge spectrum from the panorama spectrum and give the method to remove the influence of color noise through subtraction.A new signal reconnaissance method based on channel color noise suppressing is presented. The experiment indicates the method is efficient. |
