A Modified dual-mode Fusion Detection Algorithm Based on Wilcoxon Detector

针对双模复合制导中的融合检测问题,提出了一种修正的Wilcoxon检测器融合检测算法。通过对两局部统计量增加一个修正系数并使用修正的检验统计量进行判决,融合后系统的检测性能比传统Wilcoxon检测器融合检测算法有明显提高。文中给出了修正系数和融合检测器的虚警概率表达式,仿真结果表明,文中提出的算法使检测概率比传统Wilcoxon检测器略有下降,但虚警概率却大大降低,修正算法检测性能有很大改善,仿真结果还验证了修正系数和虚警概率关系的正确性。

A modified Wilcoxon detector for dual-mode fusion detection algorithm is presented. Performance of traditional Wilcoxon detector is significantly improved by using the fusion test statistic,which multiplies an extra coefficient to the local statistics. The analytic relation between modified coefficient and false alarming probability is also proposed. Simulation reveals that the detection probability decrease a little while false alarming probability improves sharply. The result also validates the relation of modified coefficient and false alarming probability.
