摘　　要：雷达部署阵地区域范围内的复杂地理环境和电磁干扰环境将严重影响雷达装备探测性能。聚焦复杂地理和电磁环境下雷达优化部署的迫切需求,提出了一种面向环境多重约束的雷达阵地部署位置优选方法。根据雷达阵地的地形地貌和电磁干扰环境,建立地理和电磁环境双约束条件下的雷达阵地选址模型;结合雷达方程,计算复杂传播地形下的传播损耗,并将目标高度层探测威力和重点区域覆盖威力作为雷达选址位置优劣的评估指标;将雷达在环境多重约束下的探测范围进行可视化展示。针对实际系统中雷达作战场景复杂、传统雷达装备部署方法考虑约束单一的问题,通过计算环境和电磁多重约束下的传播损耗、地形损耗、电磁损耗,并加入实际高程地形数据作为参考,更真实客观地分析阵地周围环境对雷达装备性能的影响。所提出的评估指标与优选方法及可视化呈现,可为多重约束下雷达装备作战效能提升提供准确、可靠、直观的阵地优化部署策略。The complex geographical environment and electromagnetic interference environment within the radar deployment position area will seriously degrade the radar detection performance.Focusing on the urgent requirement of optimizing radar deployment in complex geographic and electromagnetic environments,the environment-constrained radar position positioning optimization method is investigated.Firstly,based on the terrain and electromagnetic interference environment of radar positions,a radar position selection method under both geographic and electromagnetic environment constraints is established.Then the propagation loss under complex geographical terrain is calculated by combining the radar equations,and the detection power of target height layer and the coverage power of the focused area are used as the evaluation indicators for the superiority of radar sites.Finally,the detection range of the radar under multiple environmental constraints is visualized.The problem of complex radar operational scenarios in real systems and the single constraint considered in traditional radar equipment deployment methods is addressed.By calculating the propagation loss,terrain loss,electromagnetic loss under multiple environmental and electromagnetic constraints,and adding actual elevation and terrain data as reference,a more realistic and objective analysis of the impact of the environment around the position on the performance of radar equipment is provided,and finally the evaluation indexes and selection methods is proposed in this paper.The proposed evaluation indexes and selection methods and visualization can provide accurate,reliable and intuitive strategies for optimizing the deployment of radar equipment under multiple constraints.
