本文讨论几种实用的非参量雷达检测器在Weibull噪声中的检测性能,这些非参量检测器是用于相参检测的Dicke-fix检测器,和用于非相参检测的秩和(RS)以及秩二进积累(RQ)检测器。通过解析计算和Monte Carlo模拟,给出这些非参量检测器和相应的平稳白高斯噪声中的最佳参量检测器即相参和非相参积累器的小样本性能,并作比较,说明当Weibull分布形状参数和信噪比较小时,非参量检测器可更有效。
This article discusses the detection performance of several practical non-parametric radar detectors in Weibull noise. These non-parametric detectors are the Dicke-fix detector for coherent detection and the rank sum (RS) for non-coherent detection. And rank binary accumulation (RQ) detector. Through analytic calculation and Monte Carlo simulation, we give the small sample performance of the best parametric detectors, ie, coherent and non-coherent integrators among these nonparametric detectors and the corresponding stationary white Gaussian noise, and compare them to illustrate that when Weibull Non-parametric detectors are more efficient when the shape parameters and signal-to-noise ratio are small.
