摘要:
针对应用多普勒波束锐化技术的空地导弹制导过程,提出一种脱靶量、成像分辨率和经济性综合最优的制导律算法。基于多普勒锐化成像几何建立了方位向分辨率与导弹运动参数之间的关系模型,分析了成像约束与脱靶量之间的制约关系。在方位向平面内建立了导弹与目标的相对运动方程,将成像约束转化为导弹前置角的约束,将脱靶量约束转化为目标线角速度的约束,以导弹加速度为控制量,应用最优控制理论设计得到了导弹最优制导律。仿真结果验证了制导律算法的有效性。

Abstract:
For the guiding process of air to surface missiles applying Doppler Beam Sharpening technology, an optimization algorithm of guidance law based on miss distance, imaging resolution and economy is proposed. Based on Doppler Beam Sharpening imaging geometry, the model between resolution at the azimuth and missile's motion parameters is build and the restraint between imaging constraint and miss distance is analyzed. Kinematic of missile and target is established in the azimuth plane, the requirement of imaging is converted to constraints for lead angle of the missile, and the requirement of miss distance is converted to constraints for angular velocity of line of sight. Optimal guidance law of missile is designed by taking missile's acceleration as control variable on the basis of optimum control theory. Simulation results demonstrate the validity of the arithmetic.
