摘  要:针对传统有源雷达系统探测目标时存在的生存能力差、抗干扰能力低等问题,提出了网络雷达对抗系统无源反隐身方法,建立了网络雷达对抗系统无源工作模式下的信号检测模型。该方法在检测模型的基础上,分别计算得到了单脉冲和非相参脉冲积累条件下的系统检测概率以及分布式单元平均恒虚警率(CA-CFAR)检测概率。仿真结果表明,非相参脉冲积累检测性能优于单脉冲检测性能,在论文研究背景下,"或"融合准则优于"与"融合准则,且接收站数量越多,检测性能越好。与此同时,无源模式与有源模式还可协同工作形成一体化探测系统,这将为系统设计提供更全面的理论依据。Aiming at the problems such as poor survivability and low anti-jamming ability,etc.when traditional active radar system detects targets,this paper puts forward a passive anti-stealth method of network radar countermeasure system,establishes a signal detection model under the passive mode of network radar countermeasure system.Based on the detection model,the system detection probability under the conditions of single pulse and non-coherent pulse accumulation and the probability of cell average-constant false alarm rate(CA-CFAR)are calculated.The simulation results show that the non-coherent pulse accumulation detection performance is superior to the single pulse detection performance.Moreover,in the context of the paper,the"or"fusion criterion is superior to the“and”fusion criterion,and themore the number of receiving stations is,the better the detection performance is.At the same time,passivemode and active mode can work together to forman integrative detection system,which will provide amore comprehensive theoretical basis for system design.
