摘　　要：针对红外成像导引头跟踪丢失后无导引信号输出的情况,提出了一种飞行控制策略:即在导引头稳定跟踪过程中通过目标被动定位算法实时估算其相对位置信息,当导引头跟踪丢失后,根据估算得到的相对位置信息和惯导输出的飞行器实时位置、速度信息解算理论导引信号,以及该信号生成控制指令控制飞行器朝目标飞行。对导引头跟踪丢失后的控制效果进行了数学仿真验证。结果表明,目标被动定位结果收敛,跟踪丢失情况下飞行器飞行控制稳定,命中精度较高,具有一定的工程应用价值。This paper has proposed a flight control strategy focusing on the condition that no guidance signal is output after infrared imaging seeker tracking is lost. In the process of stable seeker tracking, the relative position information about target is estimated in real-time through passive target location algorithm. When the seeker loses its tracking, the theory guidance signal is resolved according to the estimated relative position information, real-time location and speed information of vehicle output by inertial navigation. Then the control command generated by the signal controls the vehicle to fly toward the target. The control effect of the seeker after losing its tracking is verified by mathematical simulation. The results show that in the case of passive target location result converging and loss of tracking, the flight control of vehicle is stable, and the impact accuracy is higher, which has certain engineering application value.
