现代舰艇反导中,及时、准确、有效地跟踪强机动的反舰导弹是反导武器系统中的一项关键技术。基于反舰导弹末端“蛇行机动”的运动特征,设计目标“蛇行机动”为直线运动模型和转弯运动模型的组合,并引入到构建的具有变结构的自适应网格交互多模型(AGIMM)算法和固定结构的固定网格交互多模型(FGIMM)算法中,在给定的初始条件下,运用MATLAB进行Monte Carlo仿真实验,比较分析了AGIMM算法和FGIMM算法的跟踪性能。结果表明:针对目标“蛇行机动”的强机动情况,所构建的AGIMM算法比FGIMM算法的估计精度高、位置和速度估计波动小,稳定性好,适应性强,具有一定的工程应用价值。
In the anti-missile defense of modern naval vessels, it is a key technology in anti-missile weapon system to timely, accurately and effectively track the strong maneuvering anti-ship missiles. Based on the movement feature of anti-ship missile end “meandering motor ”, the design goal “meandering motor ” is the combination of linear motion model and turning motion model and is introduced into the constructed adaptive mesh interactive multi-model (AGIMM) algorithm and fixed-structure fixed-grid interaction multi-model (FGIMM) algorithm, Monte Carlo simulation is carried out under given initial conditions, and the tracking performance of the AGIMM and FGIMM algorithms is compared and analyzed. The results show that the proposed AGIMM algorithm has higher estimation accuracy, less fluctuation of position and velocity estimation, better stability and adaptability than the FGIMM algorithm for the strong maneuvering situation of target “hunting and maneuvering ”, which has certain engineering application value .
