摘要
根据直升机载空空导弹低空、超低空作战的特点,基于最优控制理论,进行了发射后截获纵向弹道规划技术的研究,给出了纵向弹道规划技术的一种实现方法,来解决直升机空空导弹长距离低空、超低空飞行时的防撞地以及中末制导交接班过程中减少地物背景干扰等问题,并建立了仿真模型,进行了仿真分析。仿真结果表明,本文给出的纵向弹道规划技术能够大幅提高直升机空空导弹的作战效能。
According to low-altitude and very low-altitude air combat character of air-to-air missile on helicopter, the vertical trajectory programming technology of lock-on-after-launch is researched based on the optimal control theory. A method to carry out the vertical trajectory programming technology is put forward to settle the long range low-altitude or very low-altitude flight collision avoidance and the ground clutter abatement in the course of handover of guidance from the midcourse to the terminal. Then, the simulating models are built to analyze the simulation results. The results indicates that the air combat effectiveness of helicopter air-to-air missile can be increased greatly with the vertical trajectory programming technology.
