提出了一种改进的用于被动寻的导弹的基于光流带落角约束的导引规律,其具有更强的适应性和更小的落角误差,而且该导引律不要求弹目距离信息,克服了被动寻的导弹不能测距的约束.基于采用光学传感器和光流算法的测量模型,受昆虫导航的启发,利用光流信息进行被动寻的导弹的导引和控制.同时借鉴偏置比例导引律的结构,重新设计偏置项,实现导弹以期望的落角命中目标.仿真表明,拦截地面运动目标时,该导引律在保证小脱靶量的同时,基本达到期望的落角,对于测量噪声也具有较好的鲁棒性.
An improved guided law based on the flux angle with the flux angle is proposed for the passive seeker with more adaptability and smaller azimuth error. The guided law does not require the projectile distance Based on the measurement model using optical sensor and optical flow algorithm, inspired by the insect navigation, the use of optical flow information to guide and control the passive seeker of the missile. At the same time learn from the bias The structure of Proportional Navigation Law and the redesign of offset to realize the missile hitting the target at the desired angle.The simulation shows that when the ground moving target is intercepted, the guidance law can basically achieve the desired landing angle , Also has good robustness to measuring noise.
