本文研究一类用于雷达信号非相参检测的双样本非参量秩检测器的结构和性能。导出局部最佳秩检测器(LORD)的结构,发现其形式为在窄带高斯噪声中的N-P最佳检测器中引入求秩器和局部最佳秩零记忆非线性(LORZNL)。许多实用雷达秩检测器属于与LORD相同类型的结构。导出这些检测器的功效表达式。做为例子,在高斯噪声情况下,求出LORD为修正Savage检测器,并把它的渐近性能与常用的秩和、秩量化检测器做了比较。
This paper studies the structure and performance of a class of two-sample non-parametric rank detector for non-coherent detection of radar signals. The structure of the LOD is derived and found to be in the form of a look-up and local best rank zero memory nonlinearity (LORZNL) introduced into the N-P best detector in narrowband Gaussian noise. Many practical radar rank detectors belong to the same type of structure as LORD. Derive the efficiency expressions for these detectors. As an example, in the case of Gaussian noise, LORD is obtained as a modified Savage detector, and its asymptotic performance is compared with the commonly used rank and rank quantization detector.
