摘 要: | 本文证明了在形状因子已知条件下次序统计恒虚警(OS-CFAR)检测器在K分布杂波背景下能保持恒虚警的特性,分析了均匀K分布杂波背景下检测器的性能,研究了不同参考单元数的信杂比损失,对于未知形状因子,本文提出了一种有效的估计方法。

Performance Predication of Ordered Statistic CFAR Against K-Distributed Clutter |
| |
Abstract: | This paper proves that ordered statistic CFAR (OS-CFAR) detector is also ofCFAR under K-distributed clutter background,when the shape factor is known. The performanceof the detector is analyzed against uniform clutter background. The loss of SCR in the differentcase is studied. For unknown shape factor,a valiable method to estimate the shape factor is given. |
