摘要
该文基于改进的M-估计器和OSGO-CFAR检测器,提出了K-分布杂波背景下一种新的双参数恒虚警检测器,然后在均匀干扰背景中研究了这种检测器的性能,并与固定形状参数的OSGO-CFAR检测器进行了比较。结果表明,具有形状参数估计的OSGO相对于理想固定形状参数OSGO只带来很小的附加损失,同时具有更广泛的K-分布杂波适应性。
A new two parameter CFAR detector in K-distribution clutter based on enhanced M-estimator and OSGO-CFAR detector is proposed in this paper. The performance of the detector is analyzed against uniform clutter background. Compared to OSGO with given shape parameter, the OSGO with shape parameter estimation has little additional detection loss against uniform clutter background, and has broad adaptation to K-distributed clutter.
