分布式CFAR检测算法能有效扩展系统的覆盖范围和提供更高的总的信噪比,并具有可预知的检测性能。目前,对分布式CFAR检测算法的研究主要集中在理论研究方面,在理想假设条件下进行算法的性能分析比较等。本文选取两类在局部传感器采用OS-CFAR检测的分布式检测算法,对两部分散部署的雷达,以扩展覆盖范围为指标,分析了扩展覆盖范围的区域分布和比例,为分布式检测算法在实际应用时需要重点考虑的空域提供依据。最后,分析了在多传感器系统中应用分布式检测算法时需要考虑的时空对准问题,为算法的工程化应用奠定基础。
Distributed CFAR detection algorithm can effectively extend the system coverage and provide a higher total signal to noise ratio, and with predictable detection performance. At present, the research on distributed CFAR detection algorithm mainly focuses on the theoretical research, the performance analysis and comparison of algorithms under the ideal assumption. Paper selected two locally distributed sensor detection algorithm OS-CFAR detection, two radar dispersion deployed to extend the coverage of indicators, and analyzes the regional distribution ratio of extended coverage, the detection algorithm is distributed The actual application of space needs to be given priority to provide basis. Finally, the problem of space-time alignment which needs to be considered when applying the distributed detection algorithm in multi-sensor system is analyzed, which lays the foundation for the engineering application of the algorithm.
