Vertical Trajectory Programming for Air-to-Air Missile on Helicopter

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.
