The distributed CFAR detection algorithm can extend the coverage range of the system efficiently and provide higher total S/N ratio, furthermore it has predictable detection performance. At present the research on distributed CFAR detection algorithm is focusing on the theoretical reseach, and the performance comparison under assumed ideal conditions. This paper chooses two types of distributed algorithms which use OZ-CFAR detection at local sensors, and two radars located on district positions, and takes extending coverage range as the target to analyze the field distribution and proportion, so as to provide basis for the airspace needing to be emphatically considered in the practical application of distributed CFAR detection algorithm. Finally, the time and space alignment needing to be considered in the application of distributed algorithm in multi-sensor system, so as to provide the basis for the engineering application of the algorithm.
