| 摘要: |
| 在分析双通道恒虚警率(CFAR)检测系统原理的基础上,以瑞利杂波分布为背景,建立了一个三元检测的数学模型,推导出线性检波下双通道CFAR检测器的虚警概率表达式。结合公式利用MATLAB仿真,定量分析了影响虚警概率的因素,并将其与单通道情况进行了比较,得出双通道的虚警概率是归一化门限与消隐门限的函数的结论。 |

| Abstract: |
| Based on the analysis of dual channel radar CFAR detection principle,a mathematical model of ternary detection is established in Rayleigh environment,and the probability expression of false-alarm for dual-channel radar CFAR detector is deduced in linear detector.Combining of MATLAB simulation,the factors effecting false-alarm are analyzed quantificationally and compared with single channel radar CFAR detector.The conclusion that the probability of false-alarm is the function of normalized threshold and blanking threshold is drawn. |
