摘要
研究了复合高斯杂波环境中多频带相干雷达自适应恒虚警检测问题。利用Toeplitz矩阵的次对称性提出了一种新的多频带相干雷达恒虚警检测算法。所提出的算法对杂波的结构分量和杂波协方差矩阵都有恒虚警的性质 ,而且不需要杂波功率谱密度对称。该算法的检测性能优于以前提出的多频带归一化匹配滤波器算法。
The problem of multiband coherent radar adaptive constant false alarm rate (CFAR) detection against a compound-gaussian clutter background is investigated in this paper. By exploiting the persymmetry property of toeplitz matrix, a new multiband coherent radar adaptive CFAR detection algorithm is presented. The proposed algorithm ensures CFAR with respect to both the clutter texture as well as the clutter covariance matrix,and does not need the symmetric clutter power spectral density. The new algorithm outperforms the previously proposed multiband adaptive normalized matched filter algorithm.
