如何评价雷达组网系统在多压制性干扰环境下的检测性能是雷达电子战研究的热点问题之一.推导了以"信干比"表征的多压制性噪声干扰环境下的雷达距离方程,提出了利用"信干比"与检测概率的近似推算关系来研究噪声干扰环境下雷达组网系统检测概率分布图的一种新思路,并建立了相应的检测概率模型,在"三对三"对抗条件下进行了仿真.仿真结果不仅验证了模型构建的合理性和正确性,也表明了干扰机与雷达的空间对抗态势对雷达组网检测概率分布有较大影响.%How to evaluate the detection performance of netted radar system in the multiple SOJs jamming environment is one of radar EW research focus issues. The radar range equation in the multiple SOJs noise jamming environment, which characterize by SJR, is completely derived in this paper. A new thought of utilizing the approximate computation relation of SJR and detection probability to research the detection probability distribution diagram of the radar netted system is presented, the relevant detection probability model is also set up. The simulation is processed in the counterwork condition of ‘3 vs. 3’ , the simulation results not only verify the justification and validity of model, but also shows the situations between radar ECM and ECCM in space have greater effect on the detection probability distribution of radar netted system.
