摘　　要：针对二维弹道修正引信中单一制导方法修正效果相对较低的问题,提出基于代理模型的自切换二维弹道修正制导方法。该方法通过定义修正效益来定量化描述不同制导算法的修正效果,通过抽样、试验建立修正效益与飞行中弹丸相关参数的代理模型,在弹丸发射后,利用卫星导航信息解算弹丸位置及速度信息,采用代理模型计算不同制导方法的修正效益,自主切换制导方法,使总修正效益最大,从而提高射击精度。仿真验证结果表明,在某型弹最大射程角条件下,采用基于代理模型的自切换二维弹道修正制导方法,达到的圆概率误差较单一制导方法明显减小,比速度方向修正法减小32%,比落点预测修正法减小28%。该方法可实现多种制导方法之间自切换,进一步提高射击精度。A self switching 2D trajectory correction guidance method based on a surrogate model was proposed to address the issue of relatively low correction effectiveness of a single guidance method in 2D trajectory correction fuzes.This method quantitatively describes the correction effects of different guidance algorithms by defining the correction benefits.A proxy model was established through sampling and experimentation to correlate the correction benefits with the relevant parameters of the projectile during flight.After the projectile launched,satellite navigation information was used to calculate the position and velocity information of the projectile.The proxy model was used to calculate the correction benefits of different guidance methods,and the guidance methods were autonomously switched to maximize the total correction benefits,thereby improving shooting accuracy.The simulation verification results showed that under the maximum range angle condition of a certain type of missile,the circular probability error achieved by using the self switching two-dimensional trajectory correction guidance method based on the surrogate model was significantly reduced compared to the single guidance method,reduced by 32%compared to the velocity direction correction method,and reduced by 28%compared to the landing point prediction correction method.This method could be extended to perform self switching between multiple guidance methods,further improving shooting accuracy.
