针对单基地雷达难以有效探测隐身目标的问题,提出了一种基于雷达网检测性能的隐身目标探测方法。在推导雷达距离方程的基础上,结合Swerling1起伏目标模型和区域剖分方法,计算并分析了单/双站雷达对隐身目标的探测区域;然后,采用物理光学和等效电磁流法,仿真分析了结构隐身目标的单/双站雷达散射截面积,并结合典型布站方式,分别解算出等边三角形、正方形、蜂窝形三种布站方式下,单基地组网雷达和复合式组网雷达对隐身目标的探测能力和布站效率,从而甄选出最优雷达布站方式和组网模式;最后,理论分析与仿真结果验证了优化雷达组网布站的应用性和可行性。
Aiming at the problem that single-base radar can not detect stealth targets effectively, a stealth target detection method based on radar network detection performance is proposed. Based on the derivation of the radar distance equation, combined with the Swerling1 undulation target model and the region segmentation method, the detection region of the stealth target is calculated and analyzed. Then, using the physical optics and the equivalent electromagnetic flow method, the simulation analysis The single / double radar cross-section area of the stealthy target is constructed. Based on the typical distribution method of single-station radar, the single-base networked radar and composite networked radar are solved under the three distribution methods of equilateral triangle, square and honeycomb. Finally, the theoretical analysis and simulation results verify the applicability and feasibility of the optimized radar networked cloth station.
