摘要
副瓣匿影技术是一种重要的雷达抗干扰手段,副瓣匿影概率是其一项关键指标。本文在瑞利信号模型下,推导了副瓣匿影时的信号模型,得到了虚警概率的表达式,给出了检测概率的仿真方法。仿真实验结果表明,该方法能够较好地对副瓣匿影时的检测概率和匿影概率进行仿真。
Side lobe blanking technology is an important anti-interference approach for radar,and the probability of side lobe blanking is an improtant indicator of this technology.In this paper,based on the Rayleigh signal model,the signal model of side lobe blanking is derived.The expression of false alarm probability is obtained,and the simulation method of detection probability is illustrated.Simulation results indicate that the proposed simulation method can simulate the detection probability and the probability of side lobe blanking efficiently.
