Design of Anti-air Fire Control System Based on MIMO Radar

随着反舰导弹采用各种高新技术,特别在降高、增速、隐身、电子对抗等方面不断强化突防能力,立足于现有舰艇对空防御火控系统架构,以提高目前各武器系统精确、协同作战能力为目标,提出了新型对空防御火控系统体系结构,通过母舰搭载雷达发射阵列与无人艇搭载雷达接收阵列组成双基地MIMO雷达系统,利用舰载高性能服务器集中处理无人艇回传的雷达信号,可提高新型火控系统对目标的测量精度和分辨力,通过对目标进行机动识别、多维特征提取、干扰诱骗控制等处理,为不同的武器终端定制交互多模型(IMM)火控滤波器结构,可提升现有舰艇对空防御系统在低角探测、信息融合,以及抗饱和攻击等方面的能力,为舰艇综合反导系统的设计提供了一条技术途径。

By the using of new technology,the anti-ship missile has showed great progress in breaking through air defenses by low height,high speed,stealth technology,and electronic countermeasure.After analyzing the existing method of intercepting anti-ship missile on the combat ship,the paper proposes a new architecture of anti-air fire control system to enhance the weapon system's precision and cooperation ability.It combines the transmitting array loading on combat ship with receiving array loading on unmanned craft to form a bistatic MIMO(Multiple Input Multiple Output)system.The combat ship can process the signals from unmanned ship by high performance computing server,so the new system shows great advantage in detecting accuracy and resolving power,then carries out maneuver identification,multi-dimensions feature extracting,and jamming processing.Lastly customs IMM(Interacting Multiple Model)fire control filter architecture for different weapon terminals.The new anti-air fire control system would enhance the ability in low angle detecting,information fusion and anti-saturation attack,and provide a new technical approach for the design of ship's anti-missile system.
