A Guidance Law for the Image Guided Missile

目的 为便于目标识别和捕获，并避免碰框，研究在低巡航速度的条件下，减小图像导引头的需用框架角； 方法 将框架角信号和视线角速度信号进行综合，形成一种积分比例导引规律； 将其仿真结果与三点法、比例导引法进行比较； 结果 这种方法的需用框架角明显小于三点法和比例导引； 结论 该方法允许导弹以较低巡航速度飞行而不碰框，适用于各种图像制导导弹；

Aim To be advantageous to target identification and acquisition and avoid frame collision, the frame angle of image seeker should be reduced under the condition of lower cruise speed. Methods By Combining signals of frame angle and the rate of line of sight, a kind of integral proportional navigation was obtained. The simulation results were compared with those of three point guidance and proportional navigation. Results The needed frame angle is obviously smaller than those of three point guidance and proportional navigation. Conclusion This method permits the missile to fly at a lower cruise speed and doesn't cause frame collision. It can be used in various image guided missiles.
