一种适用于复合制导的中末制导弹道交接班方法

导弹武器系统的发展趋势是由单一制导模式向复合制导过渡,而中末制导的可靠交接班是复合制导的关键步骤。针对复合制导中的中末制导弹道交接班问题,在分析中末制导弹道平滑过渡约束条件的基础上,提出了一种简单有效的线性中末制导交接班算子,详细计算了平滑算子的加权系数。通过直升机载空地导弹的中末制导弹道交接班的仿真试验,验证所提方法的可行性。试验结果表明,在较小中末制导律差异条件下,所提算子可实现弹道的平滑过渡和良好衔接。

A Midcourse and Terminal Trajectory Handover Method Suitable for Composite Guidance Missiles

Transition from single guidance mode to compound guidance is the development trend of missile weapon system,and the key point of the process is to realize trajectory transition between midcourse and terminal guidance robustly. Focusing on the problem of midcourse and terminal guidance transition,based on the analysis of the constraints of trajectory smooth transition,a simple but effective method is proposed to realize smooth transition by using a linear operator. The weighted coefficients are calculated and analyzed in detail. The effectiveness of the proposed method is tested on the simulated data of helicopter-borne air-to-ground missiles. And the experimental results show that the proposed linear operator is capable of realizing smooth transition and good connection under the condition of small difference between midcourse and terminal guidance.
