机动高速目标的全向拦截制导律研究

摘要

针对机动高速目标拦截制导问题,建立了全向拦截机动高速目标的相对运动方程,推导并设计了能同时进行顺轨和逆轨拦截的全向真比例(OTPN)制导律,无需对目标加速度的估计和增加修正项即可满足对机动目标的拦截制导,能有效避免目标机动参数估计误差对制导精度的影响。数值仿真结果验证了 OTPN拦截制导律可有效拦截机动高速目标,同等初始条件下,OTPN 在捕获范围、弹道特性、过载变化、总控制量等拦截参数上均优于传统的经典比例、负比例及其扩展制导方案。%To tackle the problems of high-speed maneuver target interception guidance,the paper sets up a relative motion equation for omni-directional interception of high-speed maneuvering target, deduces and designs an omni-directional true proportion navigation (OTPN)guidance law with both head-pursuit and head-on intercepting capability which can satisfy the interception guidance for ma-neuvering target without estimation of target acceleration and addition of correction items so as to ef-fectively avoid influence of parameter estimation error of target maneuvering on the guidance preci-sion.Numerical simulation results demonstrate that the high-speed maneuvering target can be effec-tively intercepted by OTPN interception guidance law;under the same initial conditions,OTPN is su-perior to the traditional classical proportion,negative proportion and extended guidance solution in the interception parameters like acquisition range,traj ectory properties,overload variation and total con-trol volume.
