摘　　要：无人机载合成孔径雷达(SAR)具有机动灵活、战场生存能力较强的特点,它依靠SAR先进的雷达成像技术与无人机全天候、全天时侦察能力,是未来战争中监视与侦察的重要手段。由于SAR任务受无人机航线规划与飞行姿态的影响,各任务之间又存在差异性,调度易受制约而造成效率低下。任务电子系统的目的就在于为无人机载SAR的任务调度提供科学的决策依据。介绍了无人机载SAR任务电子系统的架构及任务调度方法,建立了任务调度的线性规划约束条件,通过飞行试验验证了系统的合理性与有效性。Unmanned Aerial Vehicle（UAV）-borne Synthetic Aperture Radar（SAR） has the characteristics of high mobility and high viability on battlefield.It is one of the important surveillance and reconnaissance measures in future warfare relying on advanced radar imaging technology of SAR and reconnaissance ability on all weathers and all days of UAV.The SAR task is affected by the flight planning and flight attitude of the UAV, and the various missions have lots of differences, scheduling would be restricted and inefficient. The purpose of mission electronic system is to provide scientific decision-making references for mission dispatch of UAV-borne SAR.The structure of mission electronic system and mission dispatch method are introduced, and the constraints in linear programming of mission management are established.The flight tests have demonstrated the reasonableness and effectiveness of the system.

关 键 词：无人机载SAR 任务电子 动态调度 线性约束
