摘要
基于统计和概率分布理论,逆向构造了雷达线性检波器、平方律检波器、检波后积累输出的噪声和信号检波包络,并给出了单脉冲和非相参积累下有不同的CFAR门限求取方法的结论。仿真证明构造的检波包络符合虚警概率和探测概率的统计理论,为构建准信号级雷达模型奠定了基础,有一定的实用价值。
A method of constructing the envelope of noise and signal is proposed based on the theory of statistics and probability distribution.The envelope model supports radar linear detector,square detector and post-integration detector.The conclusion is carried out that there are different methods to calculate the signal pulse and non-coherent threshold of CFAR.The simulations show that the giving envelope model obey the statistics theory of false alarm probability and detection probability,and have some practical for building radar model.
