Study on Model of Airborne Radar in One Versus One Beyond Visual Range Air Combat

为提高一对一超视距空战仿真的置信度,在考虑多路径效应、杂波、电子干扰、脉冲积累以及PRF选择的基础上,运用功能仿真法建立超视距空战机载雷达的数学模型。采用数值模拟法给出一对一超视距空战的仿真流程,以领先跟踪概率、跟踪距离、跟踪时间作为探测效能指标,运用蒙特卡洛法分析雷达自身性能和电子对抗方案对探测效能的影响。结果表明,此模型能够较好地模拟超视距空战中机载雷达的探测过程,合理可行。

To improve the simulation fidelity of one versus one beyond visual range air combat,considering multi-route radiation,clutters,electronic jamming,pulse accumulation and PRF（pulse-repetition frequency） selection,the mathematical model of airborne radar in beyond visual range air combat was established by functional simulation method.Simulation flow of one versus one beyond visual range air combat was also given out by numerical simulation method,and first-tracking probability,tracking range and time were regarded as detecting effectiveness indexes,and the influences of airborne radar performance and electronic countermeasures on detecting effectiveness were analyzed by Monte-Carlo method.The result shows that this model could preferably simulate detecting process of airborne radar in beyond visual range air combat,and it is reasonable and feasible.
