基于网络雷达对抗系统的有源探测与无源侦察双重功能，结合目标反射回波与目标雷达直达波信号特点，构建了单站接收信号的基本模型。然后，基于似然比检验准则构建单站发现概率的计算模型，给出了系统决策融合模型融合中心采用的秩 K规则判决流程。同时，基于秩 K准则构建了系统融合发现概率与融合虚警概率的计算模型，最后对系统融合发现概率计算进行了示例分析。分析结果验证了基于秩 K准则的系统融合发现概率计算模型的有效性。

Because it has dual functions of active detection and passive reconnaissance ,the network ra-dar countermeasure system (NRCS) can make use of the dual information from the target echo and di-rect wave .In this paper ,a basic signal model of the single receiver is proposed based on the charate-ristics of the dual signals and also a detetion probability model of the single receiver is established based on the likelihood ratio criterion .Meanwhile ,the decision process of rank K criterion of the sys-tem fusion center is presented and analyzed in detail .Moreover ,a fused detection probability model of NRCS is constructed based on the rank K criterion .Finally ,the simulation examples of calculating the fused detection probability are presented in detail .The simulation results show that the fused de-tection probability model of NRCS is feasible and effective .
