基于模拟的反导预警雷达目标交接搜索景幅设置研究

Optimization of Acquisition Range Based on Simulation for Ground-Based Radar

为解决远程预警相控阵雷达(EWR)和多功能地基相控阵雷达(GBR)进行目标交接时,GBR应在多大范围内,采取何种信号形式搜索捕获目标的现实问题,建立GBR目标交接搜索景幅优化模型,运用蒙特卡洛方法对该模型进行模拟求解,并从目标交接距离、目标飞行方向、目标指示精度等3个方面分析其对GBR搜索景幅的影响。首次将蒙特卡洛方法用于反导预警雷达目标交接,有效提高了反导作战任务规划效率和雷达搜索效能。计算结果表明:GBR搜索景幅大小与目标交接距离成正比,与指示精度和目标飞行方向有无先验信息成反比。

In order to explore the mechanism of the target handover between EWR and GBR,including the searching scope of the radar and the used signal type,this paper establishes optimization model about the searching map of GBR,and uses the Monte-Carlo method to solve the above model,and analyzes the influence of target handover distance,target flight direction and target indication precision on the searching map of GBR.The Monte-Carlo method is firstly applied in the target handover between radar and radar,which effectively improves the efficiency of the task planning in anti-missile operation and the searching efficiency of radar.The results show that the searching scope of GBR is directly proportional to the distance of target handover,and it is inversely proportional to the indication precision and the flight direction of the target.
