The application and implementation of ACMLD-CFAR in monitoring receiver software

Under nonhomogeneous environments, the monitoring detector using fixed threshold method of signal detecting to capture blind signal can lead to large false-alarm probability. In view of the problem, combining the thoughts of radar constant false alarm probability, Automatic Censored Mean Level Detector-Constant False Alarm Rate (ACMLD-CFAR) method is proposed to detect signal. The suggested method, compared with the existing method, have obvious advantages. The method can capture burst signal without prior knowledge of the background, what´s more it is easy to be implemented in software, and in the environment with obvious interference it can reduce the false alarm probability obviously.
