高超声速飞行器交互式多模型跟踪算法仿真

Tracking Algorithm Simulation of Interactive Multiple Model for Hypersonic Flight Vehicle

针对临近空间高超声速飞行器的运动状态多变,目前单一跟踪模型已经很难描述出目标的特性,根据多变的运动特点,将交互式多模型(IMM)算法应用于高超声速飞行器跟踪领域。该算法可以有效地根据各个模型的概率进行准确的调整,特别是对于机动目标的跟踪。文中根据IMM算法在临近空间环境下对高超声速飞行器进行了跟踪仿真。通过Monte-Carlo仿真,结果表明该算法在临近空间中具有较好的跟踪精度,同时可以提高高速飞行目标的跟踪精度。

In view of the features that motion state of near space hypersonic vehicle is variable, the single track model has been very difficult to describe the characteristic of target, according to the changeable motion characteristics, the Interacting Multiple Model （IMM） algorithm is applied to the hypersonic vehicle tracking field. The algorithm can be effective for accurate adjustment according to the proba-bility of each model, especially for maneuvering target tracking. According to the IMM algorithm, the tracking simulation is carded out under the hypersonic vehicle in near space environment in this paper. Through Monte-Carlo simulation, the result shows that the algo-rithm has better tracking precision in near space, and can improve the high-speed flight target tracking accuracy.
