摘要:

针对具有高速、高机动性能的HTV2(hypersonic technology vehicle 2)目标,对采用直接碰撞拦截策略拦截弹的中制导进行了研究,给出了一种基于轨迹跟踪预测的中制导算法。该中制导算法首先使用自适应网格交互式多模型(adaptive grid interactive multi-model,AGIMM)滤波器对目标轨迹进行稳定跟踪,获取目标运动信息。之后使用基于遗忘因子的最小二乘法对目标进行轨迹预测,获取目标预测交班点处的运动状态。最后,将预测交班点处的目标状态量作为中制导约束,并使用高斯伪谱法计算最优中制导指令。使用该中制导算法对HTV2目标进行了拦截仿真,仿真结果证明了该算法的有效性。

Abstract:

Aiming at HTV2 (hypersonic technology vehicle 2) targets with high speed and high maneuverability, the midcourse guidance of interceptor missile using hit-to-kill intercept strategy is studied, and a midcourse guidance algorithm based on trajectory tracking and prediction is presented. An adaptive grid interactive multi-mode (AGIMM) filter is used to track the target trajectory stably. The least square method based on forgetting factor is used to predict the trajectory of the target, and the motion state at the predicted handover point is obtained. The target state variables at the predicted handover point are used as midcourse guidance constraint, and the optimal midcourse guidance law is calculated by Gaussian pseudo-spectral method. The interception simulation of HTV2 target is carried out using the proposed midcourse guidance algorithm, and the simulation results prove the effectiveness of the algorithm.
