摘要
针对空间拦截制导律设计中的碰撞角约束问题,通过在全向真比例制导律中增加并实时求解时变偏置角速率的方法,设计了带约束碰撞角的全向真比例制导律(Angle-Constraint Omnidirectional True-Proportional Navigation,ACOTPN),解决了顺、逆轨拦截模式下对末端碰撞角的切换、装订和控制问题。该制导律能根据目标和拦截器的运动关系自主选择顺轨或逆轨拦截模式并装订末端碰撞角进行拦截制导,碰撞角控制精度高。AC-OTPN可通过调整理想的末端碰撞角以增强碰撞效能,使得相对质量、体积较小的拦截器同样具备较强的毁伤能力,为拦截器的小型化设计和携带更多的子拦截器提供技术支撑。
To address the problem of impact angle constraint in the design of space interception guidance law, the paper puts forward the impact Angle-Constraint Omnidirectional True-Proportional Navigation （AC-OTPN） guidance law and solves the technical problem of high-speed target interception with terminal impact angle constraint.Based on OTPN, AC-OTPN is added with time-varying bias angle velocity.It also real-timely solves time-varying bias angle rate, hoping to get expected terminal impact angle.AC-OTPN can self-adaptively choose head-on and head-pursuit interception patterns according to the motion relationship of target and interceptor.It has large capture region and high accuracy of impact angle.By adjusting the terminal impact angle, AC-OTPN can increase the impact effectiveness.Interceptors with less mass and smaller volume can also have the same kill ability.AC-OTPN provides technical support for the miniaturization design of interceptors and their ability to carry more sub-interceptors.
