摘　　要：光电载荷技术是巡飞弹的关键技术之一。提出了一种适用于方位-俯仰结构光电载荷的对地扫描方案,综合考虑巡飞弹在扫描地面目标过程中光电传感器参数、自身姿态以及运动信息等关键因素对扫描视场的影响,建立了巡飞弹飞行高度、速度、光电载荷框架角度、扫描角速度以及光电传感器视场角与扫描视场覆盖范围之间的数学模型。推导出了一种对地无缝扫描方案,给出了实现无缝扫描的约束条件,并计算了不同飞行速度及扫描角速度下的无缝扫描幅宽。通过仿真对比分析了不同飞行和扫描参数下的扫描视场覆盖范围,结果表明设计的巡飞弹载光电对地扫描方案能够满足扫描视场无盲区的要求,且巡飞弹飞行速度与光电载荷扫描角速度间存在最优匹配关系。Electro-optic payload technology is one of the core technologies of loitering missiles.A ground scanning scheme for the electro-optic payload with azimuth-pitch structure of loitering missiles was proposed to comprehensively consider the key factors affecting the scanning field of view,such as the parameters of the photoelectric sensor,the missile's attitude,and motion information during the process of scanning for ground targets.A mathematical model was established between the flight altitude,velocity,frame angles of electrooptic payload,scanning angular velocity,field of view angle and coverage of scanning field.A seamless ground scanning scheme was derived,the constraints for the seamless scanning scheme was given,and the seamless scanning widths under different flight speeds and scanning angular velocities were calculated.The coverage of the scanning field under different flight and scanning parameters was analyzed by simulation.The results show that the designed ground scanning scheme of electro-optic payload can meet the requirements of no blind area in the scanning field of view,and there is an optimal matching relationship between the flight speed of the loitering missile and the scanning angular velocity of the electro-optic payload.
