| 摘 要： | 从基本雷达方程的推导入手,给出了雷达作用距离和参数之间的定量关系。然后根据在雷达信号检测中应用广泛的奈曼皮尔逊准则,即要求在给定的信噪比条件下,满足一定的虚警概率Pfa时的发现概率Pd最大,通过对噪声的概率密度的研究,画出了曲线图。最后具体用一个例子分析说明了影响检测概率的主要因素是信噪比。

Research on False Alert and Detecting Performance on Radar |
| |
| Abstract: | The quantitative relation between the range of radar and the parameters is described on the basis of the radar equation in this paper.Through analysis on probability density of noise,a figure is drawn following the NeymanPearson Criterion widely used in radar signal detecting,ie.It is required that the biggest detection probability P d should be obtained under the condition of giren signal noise ratio and as meeting concern false alarm probility P fa .At last,a specific example is given in order to show the most important factor in effecting detection probability on radar. |
