超视距舰空导弹爬升段弹道设计

Design of the Trajectory for the Gaining Altitude Segment of the Ship-to-air Missile Beyond Visual Range

摘要:

针对超视距舰空导弹中制导的爬升段,采取两段程序圆弧相结合的方法设计弹道,给出了导弹爬升段的高度与倾角指令,并对于在圆弧间及弧与高空平飞段两转接点处出现的抖动现象,通过改变转接基准并做必需的导引指令修正,有效地解决了抖动问题。最后的仿真结果验证了所设计导引律的可行性和对于消除抖动问题所做措施的有效性。

Abstract:

Towards the gaining altitude segment in the mid-course guidance of the ship-to-air missile beyond visual range, the procedure circinal arcs were applied to design the trajectory and the altitude and the pitch angle instructions were obtained. With regard to the dithering phenomena at the points of the trajectory switch, it was effectively resolved by altering the switch benchmarks and modifying the guidance instructions. Subsequently, the feasibility of the designed guidance and the effectivity of the measures for avoiding the dithering phenomena are validated via the simulation results.
