摘　　要：在进行前视双基弹载合成孔径雷达成像制导的协同路径规划时,多导弹成像的弹道要求以运动学约束的形式描述。最优反馈控制协同制导路径规划算法根据接收机空间状态、接收机和发射机之间的路径约束规划并调整发射机弹道路径。构建有效的LSTM模型,对最优反馈控制协同制导路径规划算法生成的弹道路径进行学习训练,得到接收机空间状态、路径约束和发射机弹道的直接映射关系。模型仿真结果不仅表明LSTM神经网络应用在弹载雷达成像制导路径规划中是可行的,同时也极大地提高了路径规划的效率。In the multi-platform path planning of multi-missile cooperative guidance algorithm used for missile-borne Bi-static Forward-looking Synthetic Aperture Radar(BFSAR) imaging, it is necessary to plan and adjust the transmitter trajectory according to the space state of the receiver and the path constraints between the receiver and the transmitter.An effective LSTM model is constructed to study and train the trajectory path generated by the existing algorithms, and the direct mapping relationship between the receiver space state, path constraint and the trajectory of the transmitter is obtained. The simulation results not only show that LSTM is feasible in multi-missile path planning, but also greatly improves the efficiency.
