考虑探测构形的多飞行器协同探测与制导一体化设计

针对多飞行器协同拦截机动目标时几何构形会影响协同探测和制导效果的问题，基于最优控制理论提出一种考虑探测构形的协同探测与制导一体化设计方法。基于飞行器相对运动学、动力学方程和双视线协同探测原理，建立了协同拦截模型。在制导设计中引入视线分离角参量以调制协同探测几何构形、减小相对距离探测误差，从而在制导全程增强协同探测效果。将相对距离协同探测结果应用到剩余时间和制导律解算中，基于最优控制理论实现协同探测与制导环节一体化设计。仿真结果表明：在目标进行不同程度机动的情况下，与修正比例导引律相比，所提方法在协同探测和制导方面均具有明显优势。

Integrated Design of Multi aircraft Cooperative Detection and Guidance Considering the Detection Configuration

Aiming at the problem that the geometric configuration of multi-aircraft co-intercepting a maneuvering target will affect the cooperative detection and guidance effectiveness, the cooperative detection and guidance are considered uniformly. Based on the optimal control theory, an integrated design method of the cooperative detection and guidance considering the measurement configuration is proposed. Firstly, the cooperative intercept model is established based on the relative kinematics, kinetic equation of the aircraft and double LOS co-detection principle. Secondly, the separation angle parameter is introduced in the guidance design process to modulate the co-detection geometric configuration and reduce the relative distance detection error, so as to enhance the synergistic detection effectiveness throughout the guidance. Then, the relative distance of the co-detection is applied to solving the time-to-go and guidance law. Based on the optimal control theory, the integration design of the cooperative detection and guidance is achieved. Simulation results show that in the case of different maneuvers of an evader, compared with the augmented proportional navigation, the proposed method has obvious advantages in cooperative detection and guidance process.
