在非均匀杂波背景中和两个局部检测器的条件下,本文分析了分布式OS-CFAR检测在多脉冲非相干积累条件下的性能,与单脉冲检测,单传感器检测以及相应的最优固定阈值检测进行了对比。结果表明,多脉冲积累使分布式检测的性能有明显增强,脉冲积累数的增加使之与最优固定阈值检测的差距减小。而且尽管脉冲积累数的增加使分布式检测相对于单传感器检测的优势减弱,但是优势依然存在,并且在信噪比较低时较为明显。
Under non-uniform clutter background and two local detectors, the performance of distributed OS-CFAR detection under multi-pulse non-coherent accumulation is analyzed in this paper. Compared with single-pulse detection, single-sensor detection and the corresponding optimal Fixed threshold detection is contrasted. The results show that multi-pulse accumulation enhances the performance of distributed detection significantly. The increase of pulse accumulation reduces the difference between the detection and the optimal fixed threshold detection. And although the increase of pulse accumulation weakens the advantages of distributed detection over single sensor detection, the advantages still exist and are obvious when the SNR is low.
