摘要
针对信号搜索过程中存在的色噪声干扰及门限电平难设置的问题,通过全景频谱色噪声边缘提取及差值预处理,提出了一种抑制信道色噪声的信号搜索方法。实际测试表明,该方法能较好地抑制信号搜索谱中存在的信道色噪声,提高信号搜索方法的适用性及搜索性能。
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.
