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.
