摘要
为充分发挥先进战机在突防敌预警探测雷达网过程中的电子战能力,提出了一种多机协同航迹欺骗技术。分析了航迹欺骗的基本原理,建立了单架战机欺骗单部雷达的基本模型。在此基础上,研究了多机协同航迹欺骗的耦合关系,分析了多机协同欺骗的约束条件,给出了代价函数,建立了多机协同航迹欺骗最优控制模型。为提高模型解算的实时性和精度,对模型进行了无量纲化,并采用勒让德伪谱法对模型进行了求解。仿真结果表明,该方法可以实现对敌组网探测雷达的有效欺骗,完成突防任务。
The multi-fighter cooperation track deception technology is put forward to fully play the electron- ic war capability of advanced combat air vehicles in the process of penetrating radar net. The fundamental model of one-one deception is built based on the analysis of basic theory of track deception. Furthermore, the couple relationship of the multi-fighters cooperation track deception is discussed, and the constraint conditions as well as the cost function are built. Then the optimal control model of multi-fighter cooperation track deception is built. The dimensionless equation is given to improve the real-time performance and the precision. Finally, Leg- endre pseudospectral method （LPM） is used to solve the model. The simulation result shows this technology can be effective in the deception of radar net, and the penetration mission can be completed.
