摘　　要：以滑翔增程制导弹药为研究对象,提出基于虚拟瞄准点的复合修正算法。设计了基于落点预测模型的虚拟瞄准点解算算法,虚拟瞄准点前后分别采用级联反馈侧偏控制及基于重力补偿的修正比例导引控制,实现弹药射程增加的同时,对弹药落点进行侧向及射向控制。方案弹道及蒙特卡洛仿真结果表明,复合修正律可显著改善弹药的飞行稳定性,解决了工程实践中落点预测修正律修正指令角度波动较大的问题。此外,该算法在有效提高弹药命中精度的同时,增大了落地倾角,提高了弹药的毁伤效能。This paper takes the gliding extended range guided ammunition as the research object and proposes a combined correction algorithm based on the virtual aiming point.A virtual aiming point calculation algorithm based on the impact point prediction model is designed.Cascade feedback lateral control algorithm and modified proportional guidance control algorithm based on gravity compensation are utilized respectively before and after the virtual aiming point to increase the range of the ammunition while controlling the lateral and directional impact point.The results of nominal ballistics and Monte Carlo simulations show that the proposed combined correction algorithm can significantly enhance the flight stability of the ammunition and solve the problem that the correction angle command obtained by the impact point prediction guidance law fluctuates greatly in engineering practice.In addition the proposed algorithm not only effectively improves the accuracy of the ammunition,but also increases the terminal angular,thereby improving the damage effectiveness.
